Patriot Model CSV-3100B
10 hp Gas Wood Chipper Leaf Shredder

The CSV-3100B Wood Chipper Leaf Shredder is the perfect machine for large property owners. This chipper features the Briggs & Stratton Vanguard commercial grade engine. This quiet and smooth engine allows this unit to quickly make mulch out of thick 3 inch diameter branches. Leaves and vegetative material can be dropped in the hopper for shredding. There are no belts or pulleys to replace with Patriot’s patented direct drive system. All the power goes directly into chipping and shredding. Your Patriot will consistently make coin size chips without the need to change messy screens and covers. The large wheels make it easy to move the CSV-3100B around your property. A greasable outboard bearing insures that you will have many years of smooth trouble free chipping. The Briggs & Stratton engine features an overhead valve design for cooler, cleaner, and more fuel-efficient operation. The premium super lo-tone muffler reduces noise and the low oil run sensor reduces the chance of engine damage.

The CSV-3100B is an upgrade of the unit that was formerly known as the 10F-CSV. The CSV-3100B features the Briggs & Stratton Vanguard commercial grade engine.

The Patriot Model 10F-CSV gas chipper has been recognized by the editors of Consumers Digest magazine as a "Best Buy". The Consumers Digest Best Buy rating is awarded to fewer than three percent of the competing models in any given product category. Patriot was recognized for its outstanding performance in the "Yard Smart" section of the October 2006 issue of Consumers Digest.

WHY PATRIOT

Why Buy a CSV-3100B

Is this the right model for you?

Our model CSV-3100B is ideally suited for the "wooded lot" property owner (up to 1 acre) whose primary intent is to use this machine to chip up larger volumes of branches (up to 3" in diameter) and to occasionally shred up leaves and other vegetative matter generated during routine yard maintenance. The construction of the CSV-3100B is similar to that of the CSV-3065B. However, that extra horsepower sure makes those big jobs go faster!

Why Buy A Patriot?

Easy to Load Shredding Hopper

Patriot Products Model CSV-3100B Gas Wood Chipper Leaf Shredder Hopper

Patriot's CSV-3100B has a large hopper to allow easy loading of leaves and vegetative material into the machine for shredding. The opening at the top of the hopper is 16" long and 14" wide so you can easily deposit debris for processing.

See video of Patriot's products in action

Just for reference, the opening at the base of the hopper narrows to 7" long x 2" wide. So if you were hoping to shred whole coconuts or grapefruit, this isn't the machine for you.

Tapered Chipping Cone

Patriot Products Model CSV-3100B Gas Wood Chipper Leaf Shredder Cone

Patriot's CSV-3100B has a tapered chipping cone that makes it easy to feed rigid materials such as branches and sunflower or corn stalks into the chipper. The opening at the top of the cone is 7" in diameter so you can easily deposit debris for processing without pruning them down to perfectly straight pieces with no offshoots.

See video of Patriot's products in action

The opening at the base of the cone limits the diameter of materials to be chipped to 3".

Heavy Duty Rotor

Now that your yard waste has safely entered our CSV-3100B wood chipper leaf shredder it meets a formidable opponent, the rotor. Weighing in at just over 20 pounds and measuring roughly 14" in diameter, this is where things happen!

Patriot Products Model CSV-3100B Gas Wood Chipper Leaf Shredder Rotor

In this photo you see the front of the rotor and this unit's two chipping knives (painted blue here for ease of identification). Patriot's chipping knives are made of high quality tool steel, selected for its toughness, and are heat treated for wear resistance. Spinning past the end of the chipping cone the chipping knife is ready, willing, and able to turn your freshly pruned branches into coin-sized chips that make great mulch. These knives can reduce the volume of your freshly pruned branches by as much as 20:1. To sharpen the knives, simply remove the 3 nuts that attach the chipper cone to the housing and the 2 screws that attach each of the knives to the rotor. Sharpen using a simple wet stone or high quality file.

Click here to see Patriot chipper shredder output samples

It merits taking a moment here to point out that any wood chipper that uses chipping knives is designed to process FRESHLY CUT BRANCHES. The chipping knives are able to slice through this fresh material which makes for smoother, faster, easier chipping. We realize that everyone gets the occasional dead branch that falls out of a tree that needs to be chipped and the unit can handle those occasionally branches. However, you will be sorely disappointed if you are intending to purchase this chipper to get rid of that mountain of nearly petrified wood that your spouse has been nagging you about for years.

Patriot Products Model CSV-3100B Gas Wood Chipper Leaf Shredder Rotor

While the chipper knives do their job with a touch of finesse, the y-hammers (painted blue here for ease of identification) are the bullies of the chipper shredder rotor. These six thick, heavy, hardened pieces of steel will beat and tear apart material dropped in the hopper. Dried leaves will be pulverized and slightly greener materials will be beat to a pulp. Working together, the y-hammers provide a volume reduction of about 8:1 for leaves.

Commercial Grade Power Source

Patriot Products Model CSV-3100B Gas Wood Chipper Leaf Shredder Engine

The CSV-3100B has a powerful 10 hp Briggs & Stratton Vanguard commercial grade engine that allows you to chip a 3 inch diameter branch into tiny coin-sized chips. The Vanguard engine is engineered to robustly power this chipper dependably day after day. The engine features low oil shutdown, a premium lo-tone muffler, and a one-pull start carburetor. This commercial engine with its long stroke and high RPM level allow it to out work many of our competitors' much larger chippers.

Greasable Outboard Bearing

Patriot Products Model CSV-3100B Gas Wood Chipper Leaf Shredder Bearing

The greasable outboard bearing is one of the key features in the success of Patriot's direct drive chipper shredder design. The bearing supports the outer end of the rotor shaft and takes a significant amount of weight and stress off of the engine shaft. Less stress on the engine shaft translates into smoother chipping and longer engine life.

Direct Drive

Thanks to the use of our outboard bearing, Patriot is able to attach the rotor directly to the engine shaft. Most importantly this means more power! By not transferring power between belts and pulleys we do not lose power between the engine and the rotor. This also translates into no belts to break, fewer parts, less weight, and a more compact design.

Compact Size

Patriot's chipper shredder design is very compact. At 24" wide, 35" long, and 37" high, the unit requires little more space in your garage than a typical garbage can. The Patriot CSV is also small enough to fit into common vehicles such as mini vans and SUVs.

Light Weight

Weighing only 139 pounds the Patriot chipper shredder is one of the lightest units available. This makes the unit much easier to maneuver around your property or load into a vehicle for transport.

Side Discharge

Patriot's chippers discharge processed material out of a side discharge on the unit. Use the convenient standard collection bag provided to collect the processed material and carry it to the location of your choice. If you prefer, the airflow through our unit will allow you to discharge the material a few feet away from the machine such as into a tree line.

Most of our competitors simply discharged the processed material into a pile on the ground at the base of the unit requiring it to be collected and moved in a separate operation.

Standard Collection Bag Included

Patriot provides a standard collection bag with all of its chipper shredders. This makes cleanup a breeze and allows you to easily transport the material you've processed.

Most of our competitors make you purchase a collection bag as an accessory, if they even offer one.

No Screens Required

Patriot's chipper shredders turn your yard waste into fine mulch or composting material without the use of messy screens. This means no extra parts to keep track of and no screens to get clogged.

CSV-3100B - 4 out of 5 stars - Amazon Customer Review - Posted 03/04/15

Found this product very reliable and easy starting. Started on first pull each time with choke on. Found that having a small stick in hand to keep the items in the hopper turning allowed fast chipping of anything put in and stopped all clogs. Ran unit for at least 8 hours a day for 3 days straight without issues. Easy to move about the yard even though the yard is uneven.

CSV-3100B - 4 out of 5 stars - Patriot Customer Review - Posted 03/02/15

It does great job on branches and woody material but was disappointed with ornamental grasses and vines. I had to disassemble and clean out the housing where they were tangled around the wheel. I am now very apprehensive about shredding the grasses this spring. The handle should be a complete round handle instead of a half circle.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 01/23/15

I have had the chipper for 6 months and have used it for several hours, as we have about ten acres covered with woods. In short, I'm very happy that I bought it - the high price had put me off for a couple years, but I now wish that I had just gone ahead and purchased when I first became aware of it. There is a reason that it costs: it's a high quality machine that can tackle some pretty big limb pieces. However, I still would caution any new users not to rush the machine by jamming either limbs or brush in too quickly. I learned that the hard way. Most of the time, little jambs can be cleared with a piece of 1.25-inch PVC pipe with the motor running or at worst by shutting the motor off and removing the twigs etc using a gloved hand. However, one time, I had a major jamb that required disassembling the cutting unit - lesson learned! No more problems when I became a little more patient with shoving in limbs and brush. Note that the company sells a rod for helping to clear small jambs, but the pipe I suspect works about as well.

My first chipper. Did some product review and Patriot was tops in my price/size range. I also wanted as American made as possible. Easy assembly. Easy operation. Excellent results.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 11/24/14

This product was purchased in May 2014 and was primarily used to mulch and chip brush, saplings and tree limbs of small trees. It has provided excellent results and produces nice wood chips. I have waited to review the item until after I was able use it to mulch leaves this fall. It makes short work of leaves and yard debris even damp leaves are not a problem. Some of the key features are the powerful 10hp engine, direct drive preventing bog down, and the gas shutoff (nice when moving around the yard preventing gas mixing). Overall very happy with the item.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 10/12/14

I live on 1/2 acre which backs to a live creek. With many trees and 76 rose bushes which continually get trimmed, I had many limbs and rose canes pilling up. I use the chipper about every other month to produce nice mulch for the flower beds and fruit trees. The chipper has also been useful during the one or two ice storms received in the Dallas area. This past year (2013-2014) was one of the worst winter seasons. We had a neighborhood with fallen tree limbs on homes, cars and pool decks. once we had cleared the limbs, I used my chipper and created many bushels of mulch for all my flower beds and trees. This has saved me money from not purchasing mulch. I highly recommend the chipper for medium sized projects around your home or small ranch or farm.

CSV-3100B - 3 out of 5 stars - Amazon Customer Review - Posted 09/15/14

It works and does a good job. My issues are
- At this price point there should be a mower hitch to pull it around the yard
- Plastic hopper with screws that are hard to get to.
- Hopper needs easy to undo latches so you can get the hopper off and remove clogs
- Small bag fills up fast. Once its full the unit is clogged and its hard to clear. (See hopper removal problems)
I have used this several times and it works good at chipping. The main problem is its not that easy to move around the yard the plastic hopper has handles like you would move a hand truck, but it seams a bit flimsy a mower hitch would of been nice. The small bag fills up very fast you have to keep a very watchful eye on it one over fill and the unit is clogged. After clearing the bag and you try to restart it but its clogged to the point of not starting you will have to remove the hopper. Hopper screws from the inside of the hopper out in hard to get to locations (4 quick latches would of worked here). Last time I used it I spent a lot of time concerned about the bag getting full later in the day it clogged. It did not clear and needed to be taken apart to get it to work again...... its still sitting in the garage. If it does clog on green leafs/fresh limbs and is to hard to clear the clog let it sit a day and dry out this loosens the clog up.

CSV-3100B - 4 out of 5 stars - Amazon Customer Review - Posted 09/13/14

Reliable, durable, good value. Buy the towing attachment and make moving it easier on yourself. Though product delivers as promised, chipping with this is still a lot of work. The machine is small enough that it takes a little encouragement to get sticks through the chipper and takes a little time, while your back is bent. Leaves also require some stirring and shifting in order for them to mulch efficiently and wear a mask as it is very dusty business. The engine is also quite loud and you will need some sort of ear protection.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 09/04/14

Tough and great machine.
When I chip, I chip... all day... till dusk. Over all I had no problems. On two occasions the machine jammed, but partially due to overfilling the bag, partially my son filling the hopper with wet, muddy, leaves and old mulch. Took few minutes to clean out and get going. I was very worried this summer when I found that my storage leaked water and right into the hopper. Rusty water was drained. I filled fresh gas, took a deep breath and pulled. WOW !!! I got a start on first pull. I shut down, did some cleaning, lubricating, sharpening and off we went to chip for the day. I have gas yard machines and a start up is often a problem. I am very happy with this PATRIOT. It deserves the name

Works great with wood--took care of tree limbs left from some trees we had taken down. BUT--don't load up with too much green plants & foliage. It jammed up! I was able to follow the instructions and take it apart and clean it out--so the instructions are very clear.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 09/03/14

Purchased 11 months ago. Arrived as promised. Easy to unpack and start up. Worked as promised. Love it! Just 2 weeks ago, had a large tree lead fall out back in a storm. The chipper made a nice pile of mulch out of all the many branches and leaves that were down. Very little to haul away. Also use it in the Fall for all the leaves, with a 7 or 8 to 1 reduction in volume after shredding. Wish there was a good vacuum option for this unit, but apparently there is not. Requires a lot of bending over obviously and tedious feeding of leaves manually, but worth it in the end! Would definitely recommend!

CSV-3100B - 3 out of 5 stars - Amazon Customer Review - Posted 08/31/14

I bought this chipper with high expectations, and I'm disappointed. Yes, it usually starts on the first slow pull, and the chipped product is nice, but lots of things in-between need work, in my opinion.

Worst is the bagging system, combined with the poorly designed exhaust chute cover. The bag is too short, and hangs down to the ground at an angle from the high exhaust chute. This puts a fold in the bag, and causes it to overfill quickly. There is a large amount of leakage at the bag-chute junction, and the unneeded long bolt at the bottom of the chute will surely wear a hole in the bag quickly. Using three fairly long branches, the unit went from empty to full and locked up due to clogging in less than five minutes. My previous chipper gave far more notice of the bag being full, the bag was longer, and the exhaust was closer to the ground, allowing the bag to lay flatter.

Design details are disappointing on a unit this expensive. Several assembly bolts are undersized for the holes they fit in, and the instructions tell you to install them in a manner that will obstruct the leaf chute. (Heads on the outside, with the bolt sticking in) The design of the exhaust chute cover has already been mentioned. The chute also clangs constantly when pulling the unit over uneven ground. The curved "kickstand" is undersized and for some mysterious reason, is installed with a pin and key, instead of a bolt, causing it to move around under pressure. The "kickstand" is open square tubing without a plastic cap, allowing dirt and debris to get into the curved metal piece.

It gets the job done, but at twice the price of my old chipper, and with more frustration. I would not purchase this unit again, nor would I recommend it to a friend.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 08/19/14

I've been using the 10 HP model for over two years and am very happy with it. It's very easy to assemble and it has started on the first pull every time, except obviously when brand new, when gas has to first get to the engine! Most of what I chip is dead oak and I never chip 3" diameter limbs; even though it's capable of doing it, the engine tells you that that's as much as it's capable of doing, and I want to keep using this for many more years. It would probably have no problem with 3" softer woods. Obviously with harder dead wood the blades have to be sharpened more often, but they're very easy to remove and I sharpen them on a simple bench grinder, and I'm no professional. They may not stay sharp as long as if you had a professional sharpen them, but they definitely suck the limbs in and rip through them after I do it. This chipper makes a beautiful hardwood "mulch". It's a great machine and one where I feel if I treat it right it will treat me right.

I purchased the 9HP Briggs chipper in November 2010. I research extensively prior to the purchase of any product as I only want to buy it once. I own a certified tree farm of 43 acres and when I'm out in the field working I want dependable equiptment that produces. This machine has matched all of my expectations. I use it mainly in the fall and winter months when I thin forested areas from the smaller, undesirable trees or when pruning desirable trees. I chip up the unwanted limbs and small trees and use the chip as mulch in an appricot orchard. On my farm nothing is wasted. Niether is my time or money on inferior products. This is an exceptional machine, well worth my money. It is well made and very reliable. I follow the maintenance schedule per the directions as I do with all of my machinery and it has done a great job. It was a great investment for my needs in utilizing unwanted forest litter and recycling it to productive use.

The product arrived in a short time, in good shape and was very easy to assemble. The motor is easy to start and has plenty of power. On the negative side, it is quite challenging trying to run the fall leaves through it. I also find that It tends to plug up fairly easy when putting evergreens through it and is not the easiest thing to clean out.
By Penny, Paso Robles, CA

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 08/18/14

Bought one of these in spring of 2102. It is great when used on green limbs up to about 1.5"diameter. Zips right through. Surprisingly easy to start but I found out just recently that it doesn't want to run on the side of a hill (probably not safe anyway). It needs to be on fairly level ground. I have about 5 acres with a lot of trees and brush. A lot of oaks and red cedar. As long as the limbs are green it chews right through. It does not like dead limbs but then if I remember right the manufacturer tells you that in their literature. Most of the time, I just blow the chippings out on the ground under a bush. However, the chipper bag is very convenient if you want the chips or need to collect an move them. It also keeps the chips from damaging the turf if you are on grass.
About a year after getting the chipper I ordered the attachment that allows you to tow it behind a riding mower. Wish I had done that sooner. I have saved a lot of effort by taking the chipper to where the limbs are rather than gathering them into piles. Great, well made machine!

CSV-3100B - 4 out of 5 stars - Amazon Customer Review - Posted 08/14/14

Bought the 10 HP chipper to chip tree trimming. The chipper shout worked good and handled limbs up to tree inch fairly well. Wet or green branches will gum up the works. Pushing a mix of dry and wet helped. The shredder will gum up with green leaves. Used a garden hose while the chipper was running to clear the pasty compacted leaves from the shredder.

Over all quality is grate. The plastic hopper/handle is a question mark. How well it holds up is to be seen. Assembly was fast and easy.

Over all for a "SMALL" chipper this chipper works well!

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 08/14/14

Though relatively small and portable, the Patriot chipper is a powerful and highly effective machine.
I purchased a Honda engine because I have several of the type and they are all easy to start but was concerned that the pull start would be difficult to operate because there is no clutch and the entire flywheel spins. However, the machine usually kicks off with one pull even after sitting unused for months.
Be careful when replacing the knives. My nephew moved the flywheel when he shouldn't have and almost cut off his finger.
I liked purchasing from a Wisconsin company which is local for me.

I got this machine as a gift from my wife. It was delivered nearly a week earlier than scheduled. Assembly instructions were clear and easy to follow, and assembly took me roughly two hours (I am not what you'd call a handyman). I've been working through several piles of old brush, dead branches and leaves. The wood chips are nice, even, and roughly dime sized. Leaves produce a very fine dirt like mulch. So far everything that fits down the chute(s) the machine has processed without trouble. I've only had one problem. The machine starts well when cold, but after warming up if you need to stop to empty the bag or clear a jam it does give trouble. It usually takes at least three tries to get restarted plus fiddling around with the choke. Other than that I am pleased with it. I've never owned a chipper/shredder before this one so I can't compare it to anything, but I'll say this much: after using this machine for a couple months I wish I'd bought one twenty years ago.

I used this to clean up the results of a hurricane that went through our area. It easily took care of small branches, leaves, etc. As others have said.. it has about a 3 inch throat. You will need to cut things down to that size and be careful with Y-shaped pieces, etc. I should point out that after about 15 hours the engine on mine blew out-- oil went everywhere. I took it to a registered Briggs and Stratton shop who determined that it was faulty and they replaced it for no charge.

So... remember-- this is not the kind of machine that can deal will really large items, but its great for small stuff. It produces lovely mulch for gardens!

I bought this about 1 1/2 years ago. It was easy to assemble. Just follow the directions The Briggs and Stratton engine started on the second pull and has every time since. I have many maple and oak trees around my house - hard wood - and it has been very effective. After over a year of use, I'm happy I made the purchase. Do routine maintenance, use common sense, and I think you'll be happy.

This machine is a beast. It is self feeding and will pull the limbs you are chipping right out of your hand. Even though it has a recoil starter, it does start easily.

I can't say enough good things about this chipper, starting with the on time delivery, the unit was packaged very well and the instructions were clear and informative it took about an hour to assemble and started on the second pull.

I have used the chipper 5 - 6 times and it preformed as advertised and beyond, the knives are still sharp and pull the debris in just like the first day. I would be remiss if I didn't recommend this machine to my friends.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 08/08/14

I have about 3 acres of property with mature trees and low growth (e.g., forsythia, etc.). Over the year, there is a steady stream of dead branches, the occasional tree trimming, the occasional tree that needs to be taken down, leaves in the fall season, as well as occasionally cleaning up from storm damage.
My goal is to recycle all the organic material and pour it back into mulch around fruit trees and leaf mulch for my patches of berries and garden vegetables.
I debated purchasing a chipper-shredder for brush and small branches (~ 3-inch diameter) or occasionally renting a higher capacity chipper-shredder (which would also accommodate larger diameter (~6-inch) branches. Rental of such chippers is on the order of $200 per day and $600 per week. I swayed to the side of purchasing a residential chipper-shredder (on the order of $1,000), as I did not want to see huge piles of brush accumulate over the year and then try to tackle them at one time. Obviously, a residential chipper-shredder cannot handle larger diameter branches, thus, my pile of logs for my fireplace is a little larger.
I purchased the gasoline-powered Patriot CSV-3100B Chipper-Shredder in September 2013, which comes with a B&S 10 HP engine. The packaging was secure to avoid damage during shipping. The assembly of the unit took less than 30 minutes, which is essentially installing the plastic hopper and the chipping cone on the unit, filling the engine oil, and lubricating the grease fitting on the shaft.
The B&S engine is bullet proof. I have never had a problem in starting it up cold (on full choke) with one pull of the cord. Starting it up warm is equally easy, but the choke has to be adjusted to accommodate warm starting. Having been exposed to commercial chippers that throw material out of a chute, originally, I was not sold on the idea of chipping into a collection bag for the CSV-3100B. When the bag is full, the engine is shut down for the bag to be removed, emptied, and re-attached. The whole process is unobtrusive and takes a minute or two. You should definitely work with larger collection bags. I empty the collection bags into a wheel barrow and then use the wheel barrow to distribute the chipped material.
Shredding leaves and thin woody debris is done through the hopper. There is significant suction on dry leaves, pulling the material directly into the flails. Mixing in thin woody debris or damp leaves, however, tends to clog the hopper and it is necessary to use a stick to dislodge the material in the hopper so that it falls through the hopper and into the flails.
Unfortunately, I am not always grinding leaves immediately after they fall, and thus, I find myself dealing with damp leaves. I would not use this equipment on soaking wet leaves, as I think you will be struggling with continually clearing clogs from the chute where the collection bag is attached. Even with damp leaves there is build up in the chute where the collection bag is attached and you will have to watch that chute does not become clogged. Also, I find that shredding damp leaves yields buildup of wet material on the walls where the wheel rotates and where the collection bag is attached. To clear this, I keep several branches that I chip through the chipping cone; adding “fiber” to the diet clears blockages and cleans the pipes.
The grinding of larger diameter woody debris and branches up to 3 inches in diameter are fed through the chipping cone. The branches need to be trimmed so that they are more or less straight. Thus, one has to keep this in mind while trimming up brush so that you do not have to stop and tend to this step during chipping.
There are 2 blades on the wheel to chip branches. When the blades are freshly sharpened, branches are pulled down the chipping cone; one should not have to force or push branches down the chipping cone. If you find yourself pushing branches down the chipping cone to engage the blades, the blades likely need sharpening. The manufacturer says that blades should be sharpened after 8 hours of use; however, I find that the type of wood that you chip plays a big role in how quickly the blades become dull. From my experience, dealing with dead wood or wood that has dried for some period of time tends to dull the blades more quickly. This past weekend, I was chipping for less than 2 hours when there was a noticeable change in the capacity of the chipper to pull branches down the chipping cone. I would avoid trying to chip branches when the blades are dull, as this places unnecessary pressure on the shaft which can ultimately lead to the misalignment and cracking of the shaft.
Access to the chipping blades on the wheel is straight forward; it requires removing the 3 nuts that secure the chipping cone to the unit and removing two screws that secure each blade to the wheel. Unfortunately, I do not have access to the equipment or experience in grinding steel blades to avoid excessive heat and maintain the original angle on the blades. I have invested in a second set of blades and accept that I need to visit my local lawn mower repair shop for sharpening the blades. In general, I find myself chipping branches once a month or once every 6 weeks, and I consider it part of the routine to remove the blades and have them sharpened. Thus, the cost of sharpening the blades on a frequent basis should be factored into the routine engine maintenance and greasing the shaft. I am quickly approaching the time when I will need to replace both sets of blades. The cost of the blades is $70 from the manufacturer.
In theory, the flails should also be serviced. Accessing the flails is a little more involved process, which I have not tackled yet. I have only been using the flails to grind leaves and thin woody debris and I have not seen deterioration in the operation of the flails over the time that I have owned the machine.
Overall, I have been pleased with the operation of the Patriot product. I am accepting of the limitations of residential chippers such as these. It fulfills my need to chip/grind organic material once a month or once every 6 weeks and pour this organic material back into the soil.

We live on 3 acres of former pasture land that was dotted with small trees, including fir and wild fruit trees. This shredder has performed as advertised, with no problems chipping all branches that fit into the chute. The side discharge is very convenient for attaching the collecting bag or directing chips into a pile. It always starts with one pull. The blades seem to stay sharp for a long time, and are easy to remove for sharpening. The only small drawback is the size of the hopper chute, which narrows down to a few inches and makes it a little difficult for irregularly shaped small branches to feed by gravity from the hopper. Just requires a poke or two.

I picked this up after an intense Winter storm leveled several large branches on my property, and have used it several times since here and helping neighbors. The ability to mulch and compost the products rather than drive to the county dump was the goal, and I'm glad I picked this particular machine. It is big enough when used with a small chainsaw, and it is has been very reliable. I'm normally more of a Honda fan, but the B&S engine has lots of power and always starts on the first pull. Note: I always run the gas all the way out (a must for Honda, but I think the B&S benefits too).

I was initially drawn to the idea that Patriot is an American company, and was looking for gear that would last years instead of months. This purchase was on target. No issues with blade life, and the engine is strong and reliable. Have a wrench nearby to remove the cone for clogs - an exercise that will be infrequent after operating once or twice. Safety features are good. I recommend this machine.

This is a great tool! During fall leaf season I use it 2-3 times per month. It produces excellent mulch that I collect in the cloth bags and spread in the flower beds and garden. I no longer put leaf bags on the street for the city to pick up. There is a learning curve in putting material in the hopper. Too much at once will obstruct the hopper requiring manipulation of the leaf bolus with a rake handle or a stick. It is rare to have the shredder damage the rake handle but if it does there is no real harm done. I have had no success with the tool that Patriot sells for this purpose. It works better to manipulate the leaf bolus side to side rather than trying to force it downward to the shredder. I usually rake the yard in fractional areas and then put the material in the hopper by hand, releasing it slowly rather than dropping a large bolus at once. I have been very happy with the operation of the machine. It cranks easily with one or two pulls. I have not used the chipper a lot but I have no real complaints. It doesn't handle limbs that are crooked very well- they get stuck in the hopper.

I bought this chipper shredder in December of 2012 and have never regretted it for one minute. It does just what the seller says. It has plenty of power with a well-known engine and I would suggest that you buy the hitch for towing on the tractor as that was a real blessing. If you need help the people at Patriot are very knowledgeable and helpful for questions and answers.

I bought the 10HP Patriot for my husband. He said it's very powerful, chips great and easy to maneuver. The chips are smaller than the ones from a large commercial tree chipper. He said that it usually starts by the 2nd pull but requires a lot of strength to pull the cord and wishes that the engine came with a compression release. I told him that it's more practical than going to the gym.

We have three acres of land, some of which got very overgrown while the children were growing up, and after trying and failing to make much headway with hand tools I ordered the Patriot chipper/shredder. It arrived well-packed and with very clear assembly instructions. If you've bought anything made overseas recently you understand how refreshing clear instructions can be. Assembly took about 45 minutes or so. I took it out to my accumulated brush pile (somewhat taller than I am and about fifteen feet long) and in about two hours the pile was reduced to chips and spread on my garden for mulch. At that point I was so impressed with it's performance that I began to throw a lot of other neglected stuff into it, some of which was too soggy and bound it up. Back to the clear instructions in the manual, a couple of wrenches, a little work with a stick and all was well again. I've never bound it up since. In three years that's the only problem I've had with this unit. The construction is very robust and operation has been faultless. It's been well worth the price. I'd be glad to recommend it to anyone.

I really like my wood chipper, am amazed at how big the branches it will chip. Make sure you change your bag before it gets too full otherwise the insides can get jammed up. If it does get jammed up make sure you turn it off before you try cleaning it out. You won't have a problem if you empty the bag before it's too full.
By Laurie

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 07/30/14

I bought this chipper back in 2011. It still runs just as good in 2014. Very powerful, and it starts up on the first pull most of the time, and definitely by the second pull all the time. Definitely get the bag that goes with it, if it is not included.

I bought it because I have a lot of trees on my property, and I am always having to get rid of branches and was sick of throwing them in the woods. It will definitely handle the thick 3inch branches, but you can hear the engine slowing as it is ripping through them. I just hold on to the branch, pull it back every couple of seconds to let the engine get back to speed, and there is never a problem. Small stuff it eats up with ease. It works best on fresh cut stuff, as opposed to dried out stuff that has been sitting around for years (it will still chip up the old dry stuff, but it takes longer because the dry pieces will bounce around in the tube until they are chipped). The design allows for the cutting device to grab the branches and pull the stuff in, so often I just drop long branches in and let it do its thing. I dropped in 16 foot pine branches, and just guided it in, but otherwise it did the job.

Definitely worth it to me. I think it is better to pay for more power than to get a lower powered one and have to take longer or really strain the machine.

Great Chipper ! Glad I purchased the 10HP for the power and ease of chipping old dried branches. The engine starts easily and has plenty of power. The CSV-3100B has a heavy duty bearing that really requires a Puller in order to remove it and access the Y-hammers. I have used the machine aggressively shredding older dried branches by dropping them into the Hopper. So I have rotated and now replaced the original set of Y-Hammers. In my opinion, the wear and tear has been very acceptable and justified based on the heavy duty use I have been putting it through.

Great machine and well worth the price.

Overall good design, solid construction, and with plenty of power to handle the material it is designed for. I've had it for about four years, and it has performed as advertised, giving no problems. My only complaint would be that it's harder to move than it has to be because the handle is incorporated into the plastic chute, close to the center of gravity, which makes it awkward to move, especially over irregular ground. It needs a sturdy handle that stands out far enough from the machine to move it more easily. It's also a good idea, for more efficient operation, to remove and sharpen the blades after every ten or so hours of use. It has been my impression, listening to others talk about their chipper-shredders, that it would have been a good idea for them to have spent some extra money to buy the Patriot machine.

I spent $500 to hire a tree service to chip up 15 years of brush piles in my back yard. Though that amount is cost effective compared to the price of Patriot Products 3100B Chipper/Shredder; I bought one to eliminate brush piles themselves. It works as advertised making short work of tree branches and bush trimmings. Engine is very powerful with deep, mellow exhaust sound. I just love listening to it. It starts on the 1st or 2nd pull, though pulling is not easy because of the weight of the flywheel/cutter. The mulch it produces is a nice, small size which stays in place and decomposes quickly. It also is very effective at shredding leaves in the fall, shrinking my compost pile and speeding compost production. The major drawback to this chipper is the need for the branches and limbs to be nearly straight. So i spend a lot of time cutting them into straight pieces. So a wider hopper-like feeding system rather than a cone would be nice. All in all, a very good machine and I would recommend it.

A pricey but high quality chipper. Handles most chores with satisfactory results. The unit will stall if the bag is not removed before it is filled to capacity, then it is difficult to unclog the machine. This is the only operational problem with the chipper. Only disappointment with the machine itself is that instead of semi-pneumatic tires, it came with solid rubber tires. This short coming does not affect the performance. I did not rate it five because the replacement knives are very pricey as are most of the accessories. I can do without most accessories but knives must be replaced.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 07/28/14

I've had my CSV-3100B for several months and I've put around 8 hours on it so far. During a long session, it chips and shreds without any hiccups or slow-downs. I use mine primarily for leaves and light brush and it tears right through them. The chipper itself is easy to maneuver around my yard and the Briggs & Stratton engine starts with a single pull. Assembling the CSV-3100B is not difficult, but I do recommend having another person on hand to help as it is very heavy and you do have to put one of the wheels on yourself (Patriot included an amusing note that they ship with one wheel in a different package to get around UPS weight restrictions). The manual is comprehensive and written in a fun, conversational tone.

One tip I'd give is when you're shredding leaves, pour the leaves in; don't dump them. This tip is in the manual, but it's really important. If you dump the leaves in, you'll usually end up having to get a stick to push them down into the hammers. If you grab a handful and slowly pour them in, you can keep going with no interruptions.

The Patriot CSV-3100B has proven to be an outstanding tool - my grandfather always said buy the best tool you can afford and it will serve you well - and that is true of the Patriot Chipper/Shredder.

I wanted a chipper/shredder that could mulch our landscape and fruit tree trimmings for top cover and for composting use. We are trying to recycle back into our land. I researched a variety of brands and units and landed on the Patriot. Prioritized reasons were: 1) Power to unit size ratio, 2) Up to 3 inch wood chipper and 3) Made in the USA. Reviews on Amazon and other tool sites were very positive averaging to the 4.5+ range. Those that were negative tended to be on delivery service issues or lack of reading instructions and NOT the Patriot unit.

The Patriot chipper was delivered on time by Amazon Prime. Very easy to assemble with basic hand tools. The instructions were clear and easy to follow. Patriot offers a help line but I did not need it. Just fill with 10W30 oil and gasoliine and in one pull the B&S engine came to life. I have run about 50 hours over the last year - fruit tree leaves and branches, landscape trimmings etc through the unit and it eats everything I have fed it and spits out really nice mulch. We have used the mulch in our raised beds, around the fruit trees and in our compost bin - its great to give nutrients back to the soil as well as building up the soil till.

This unit is NOT an industrial chipper. If you are mulching a forest of trees or have branches over 2 inches this is NOT the unit for you. If you want a tool that is USA made, powerful yet portable and a reliable chipper for home or small farm uses like ours - this is your chipper.

There are other variants of the CSV-3100B including a Honda engine and electric start and different HP engines with different model numbers and price points . For the value, this unit is the one that offered the best over all value for my needs/uses. I will definately by Patriot again.

Have had this product for a year and it operates as advertised. It's able to process a tremendous amount of leafs in less than half a day and never more than a tank of gas. Shredded product is good for use as mulch. The chipper is great as well, as long as you follow the operating instructions (which are common sense). Keep the blades sharp, I just use a file, and it'll handle anything within the described dimensions.

I purchased this chipper because I wanted to add some coarse materials to my compost pile and pruning my trees in the spring gives me a lot of the basic resources to do so. Before the chipper, I had a large pile of branches to dispose of each year. Now I have a nice pile of compost to place in my garden and flower beds. We've also had fun with it as we tried apples, corn cobs, corn stocks, and broccoli stocks in it. We barely finish using the chipper and then the cows, chickens, and turkeys show up to clean up the edible parts. I am planting more corn this year just so I can run it through the chipper.

The chipper cleans up nicely with very little effort. This is my third summer with the chipper and it starts easily every time. I store it in a shed so I am sure that helps keep it in good operating condition also. I have sharpened the blades twice and it is not difficult to do.

I have not used any other chippers and so I cannot compare this model to others.

Patriot probably makes the finest chipper/shredders out there. You get what you pay for and you pay for this one! I can drop a 2" - 3" limb in the chute and that thing is essentially sucked in by the chipper blades eating it up and spitting out 1 to 2 inch chips. I am very impressed by the heavy duty build and overall quality of this unit. I don't see anywhere that corners were cut to save weight or to be just "good enough". Assembly is a breeze as long as you follow instructions and pay attention to what you are doing. A little tip, when attaching the hopper, get some foam or some other material to block the bottom of the opening into the chipping/shredding housing. If you drop one of the nuts it doesn't drop in and you don't have to turn the machine upside down to get it out! Unit is easy to move around and position where you want it. I have the 3100B which has the 10hp Briggs engine and it starts with first pull every time. Be careful, this engine uses a high compression start and its about pulling hard and steady, not as hard as you can and fast. My first time pulling on the cord I about broke my arm trying to yank as hard and fast as possible. Also works great as a leaf shredder, takes a bazillion leaves and makes a nice manageable pile that gets composted back into the garden. This machine as my title states is "BAD A**"!!

After receiving shipment, engine would not start. Most likely cause was bad oil level sensor which prevents starting if oil is low. Oil level was fine, but no spark. Long story short, the president of Patriot products personally delivered a new unit to my door and took the other one away. He had me start it and gave me a rundown on operation and maintenance procedures before he left. I've used this new unit close to 20 hours of major chipping and it's fantastic. It eats 2 inch saplings as fast as I can feed them into the chute. Chips are roughly 1/2 inch. Starts on first pull and is easy to push around the yard. Be careful, not to overfill the mesh chip bag or to allow the bag to block the exit chute on the chipper. This will clog the unit and require disassembly of the chipping chamber. If you take those two simple precautions, this thing will run all day without a hiccup. Very highly recommended. One other suggestion is renting one first to try it out. Ask Patriot where to do that in your area. You won't be disappointed and you cannot beat the customer support. I know!

CSV-3100B - 4 out of 5 stars - Amazon Customer Review - Posted 02/26/14

I picked this one because I don't have a lot of storage space and this machine seemed to pack the most capacity into the smallest envelope. Overall I'm happy with it. It's first job was to chip oleander trimmings. Between pruning and chipping, I was able to fill 6 Herby Curbies (2 per weekend, over 3 weekends) working 4 hours a weekend.

Impressions:
The motor is top notch. It is supposed to be relatively quiet, but make no mistake about it, the thing is loud! The motor starts easily when cold, not so easily when hot. It has a throttle so the motor can be throttled down when not actually chipping, for instance when emptying the bag.

The hopper has a narrow throat and material bridges easily. This is probably my biggest source of dissatisfaction. Have a stick handy for clearing jams. Loosening the jam by lifting seems to work better than pushing it through. I like to use leftover PVC pipes because accidental contact with the flails just breaks off the end, with no tendency to pull the pipe into the machine.

The machine does not like wet material. Wet material tends to clog the outlet. You must not clog the outlet as it can lead to a stall with material still in the machine. A failure of this type will likely result in some degree of dis-assembly to clear out the machine before it can be restarted.

It does not like dry or dirty material. If you use the thing to chip roots, the knives will become instantly dull (said experiment performed by my spouse).

Sharpening the knives requires power tools. Knife maintenance is part of the cost of owning this machine. Personally I've had good results using Grizzly wet grinder. They aren't as pretty as new after sharpening, but they cut almost as well.

The exhaust faces down and will burn your lawn. Don't use it on the lawn.

If you use it on hard surfaces, it helps to have some heavy blocks. The vibrations will cause the machine to walk around.

All in all, I am happy with the machine and it has been quite helpful in maintaining my yard. There is a definite learning curve with this machine. My biggest gripe is the easily clogged hopper which is why it only gets 4 stars.

I bought this mostly to chip/shred scrub oak and it works great. I did get it jammed early on but put too large of a branch in the shredder & didn't have the choke on full blast. Read later that at my altitude 7500 feet choke has to be full on for motor to work right. I have also used it to chip pine tree branches and have been pleased but I've been very careful about cutting branches up first so I'm not stuffing too much in at once. This is definitely a home machine & not to be confused with those big industrial ones. I would buy this product again.

After researching all the reviews and ratings of several chippers as a gift for my husband, I finally chose the Patriot CSV-3100B on the basis of so many outstanding reviews. We have a large garden and use organic gardening methods so he wanted a chipper that would take brush, corn stalks, huge sunflower stalks and put it as mulch back into the soil. He had been borrowing a friends large, well known brand chipper but because of the top heavy weight distribution, nearly had a serious accident when they were unloading it from the truck. So I decided he needed one of his own and started the search for the right one even though I know virtually nothing about chippers. The reviews of the Patriot very important to the selection process.

My husband is thrilled with it and how easy it is to handle and move since the center of gravity is low. The engine is easy to start, very powerful and produces a very fine grind. He states it's quality produced of excellent materials. We are also pleased it was manufactured right here in the US. He is singing its praises and would recommend it to anyone thinking of purchasing a chipper.

I had to really rationalize this purchase. The cost was way beyond what I wanted to pay for a chipper shredder, but I love it. It used to be tat I would avoid pruning because I couldn't deal with the branches. That resulted in som pretty wild looking trees and shrubs. No more. It works well, is very powerful, and produces great, fine mulch. I love it.

It's changed my garden forever. Before the garden was littered with branches and other material that wouldn't compost on its own. All of this is now gone, having been handily dispatched by "The Beast". It's very solid and if you're an American, you can be proud to purchase this fine domestic product. Bravo to Patriot Products.

Back to causing shredder-envy with the neighbors now...

IMPORTANT UPDATE: In order to replace the rotor hammers you will need to remove the rotor assembly from the crankshaft--not an easy undertaking given that the instructions in the manual DO NOT WORK, will lead to frustration, and may damage the unit. No amount of prying per the manual works.

1) Buy a fully-threaded 9/16-18 2" bolt, preferably made of strength 8 steel, preferably longer. It's important that it's fully-threaded. You may have to order one, since most stores only carry 1/2" and 5/8" bolts.
2) Buy a 3/8" steel rod 5" in length. I used an old drill bit. Any larger diameter might damage the crankshaft threading, any smaller and it may bend under load (see below).
3) Follow the directions in the manual which explains how to get the metal casing off, exposing the rotor assy.
4) With the casing off, remove the 5" bolt that secures the rotor assy to the crankshaft.
5) Drop the steel rod into the hole. It will seat itself against the bottom of the crankshaft's threaded female well.
6) Screw the 9/16th" bolt on to the rotor, which is also threaded specifically for rotor removal. You will need to screw it all the down. As you do, it will make contact with the steel rod and slowly push the rotor assembly straight off of the crankshaft.

I have a very specific skill set which requires lots of chipping and shredding things. Anyone in my business, and there are not many of them, know that cleaning up is the hardest part. The patriot CSV-3100B really makes short work out of tall projects. It can be a little cumbersome with wide loads though. I would highly recommend this product.

Have just assembled and used my Patriot 10HP Chipper/Shredder (with my wife's help) and it is fantastic. I have never owned a product like this so had nothing but product reviews of other companies offerings to compare it to. There are no belts to break or replace and it certainly is not underpowered for winter debris and the early spring growth I need to create mulch from. Hats off to the folks from Pewaukee WI.

I am very satisfied with everything about this purchase. This Patriot CSV-3100B 10 HP Chipper has very strong reviews that are well deserved. Everything about the transaction went smoothly. The unit was shipped timely and was received in 2-3 days in perfect condition. It was very well packed with very good instructions on how to assemble. The unit started easily and performs extrremely well. I was glad that I chose the 10 HP unit with the Briggs/Stratton Commercial engine. I have used the unit several times and each time have been completely satisfied with it's performance. After doing a lot of research and comparing of different units, I am glad that I chose this product and I highly recommend this product for anyone who is looking for a first quality wood chipper.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 12/31/12

Did quite a bit of research on the different brands and related cost. The 10 HP was selected since it was more powerful than most and not that much more in price. Engine started on first crank and have used it 3 times since purchased to start clearing new lot 1 acre. The chipper chute is narrow so the items that are being chipped need to be trimmed to fit down the chute.

Be sure to put oil in the crankcase because when you check it looks like there is oil in the engine but there is none. Patriot Products is very clear that oil needs to be added so don't be fooled.

Delivery was quick and simple and assembly was just as easy.

The CSV-3100B arrived in two boxes and took approximately 30 minutes to assemble. The assembly instructions are well written and easy to follow. After filling the B&S engine with fresh fuel and oil it fired up on the second pull. I let the machine warm up for a few minutes before I began to feed it. After nearly 8 hours of use over 2 days here are my pros and cons:

PROS:
- Powerful machine, has no problems handling 2" dry branches
- Easy to move, one side of the hopper has molded handles which makes it simple to tilt the machine back and push/pull it into place
- Makes a beautiful shred product. Most of our leaves were very well shredded. The average size was less than a US Dime.
- B&S engine fired up without any problems. The pull start requires a nice, steady pull.
- Engine throttle allows the user to throttle down the unit when they aren't shredding. Greatly reduces noise levels.
- The standard bag is easy to move and unload. Larger bag is nice, but can get quite heavy.
- Unit includes a pair of safety goggles. I already own several pairs, but its a nice touch by Patriot to stress the importance of eye protection

CONS:
- Small branches hidden in your leaf piles can cause "bridging" issues in the feed hopper, no tool is included to help clear clogs
- Branches must be fairly straight to feed into "cone of destruction" (kids name for side feed)
- Bag attachment point appears to be a bit "rough." If the bag is not perfectly placed the unit will blow shredded product all around

To expand on a few of the cons - unclogging can be a challenge at first. I found that using a straight piece of wood (in my case a 1.5" dia branch) to stir the material at the point the feed hopper narrows worked very well in clearing the hopper. The unit creates quite a bit of suction so the issue was usually related to small branches in the leaf pile bridging the opening and causing a backup well above the actual shred point. I also noticed that feeding it a bit slower helped greatly reduce this issue.

The area that the bag attaches to the machine needs a bit more work. I'm looking into fitting it with a rubber or plastic baffle/collar that the bag would fit over. This should make operation a bit tidier and result in less shredded material being blow around the unit.

The Patriot CSV-3100B is not perfect, but the "CONS" are so minimal that they come no where near negating the usefulness of this shredder. It does exactly what you expect it to do and does so very well.

CSV-3100B - 5 out of 5 stars - Amazon Customer Review - Posted 11/11/12

Worked as advertised. I have a 1.5 acre lot and have been accumulating a large pile of limbs and small trees so I finally broke down a bought the chipper. Not cheap but it handled everything I threw at it. Tree limbs that were very crocked did require trimming to get down the shoot but some straight small pine trees less than 3" at the bottom when thru limbs and all. Would a cheaper chipper have worked, don't know, but I am very pleased with the Patriot Chipper and nice to be able to buy something still made in USA.

My Patriot chipper shredder started on the first pull. I put it to the test right away but didn't really know what I was doing. Don't put too many twigs through the shredder part of the machine and don't try chipping too many evergreens with it. Believe me...the evergreens have a pitch/gooey sap and it creates a glue type substance that makes everything else stick to the inside of the chipper housing. It will build up to the point that it plugs completely and lugs the engine. After a complete tear down and cleaning...which was not that easy to do (the plug inside was really a hard mess), I sharpened the knives and put it back together. It chips and shreds like it is suppose to. It gobbles up hardwoods like nothing. The mulch that it makes is really nice. I like the Patriot chipper. Just use good sense on what you chip. Any good green hardwood 3 inches or less and any and all leaves in the shredder part and all will be fine.

Received the chipper in three days (great shipping time). Put gas and oil in and fired it up on the first pull. Spent five hours chipping and this machine is incredible and smooth. I will know more after using it a few more times but so far it is worth every penny. I went over the whole machine and it is a very well built, solid chipper. Set up is easy but it is a bit heavy to lift in a pickup (two man job)hence being well built. This is my first chipper and I am glad I went with the Patriot after reading the reviews on a couple of the others I was leaning towards. There wasn't a branch that it didn't eat, be careful as the bigger ones will get pulled right out of your hands. The mulch is a perfect size and my wife loves the fresh mulch for her garden, flowers and trees. Great machine!

I have had one of these for about 15 years and replaced the key on the flywheel and the plate that holds the chipper blades and knifes, but over all it is a very good machine along with the vacum attachment it makes easy work of leaf clean up and reduces volume by 40% or so , but remember not to vacum wet leaves or they might clog in the tube, I use a sillage rake from tractor supply and dump them in the hopper. you won't be disatisfied if you buy one.

Good for small brush or properties 1 acre or less. found it to be a bit smaller than expected. You should have a chain saw handy for curved branches.

Fired Up in a short time and we were chipping away..... Leaves branches and everything in between. I have used it 5 or six time and it has fired up every time with very little effort. Some times the leaves will clogg up in the hopper and I have used a stick to keep it free fl0wing and the branch chipper needs straight branches that need trimming to fit

Easy assembly. Engine started on first pull. Quickly chips even large branches. Only down side is that the gas tank is under the hopper and it is awkward to fill.

Quite simply put you cannot find a better value than a Patriot wood chipper. I have had mine about 20 years. They used to be sold at Home Depot long ago, but discontinued their relationship because the Depot used to take back everything for any reason and they got tired of accepting return units with nothing wrong with them. Anyway, the true beauty of the Patriot chipper besides it's lnongevity, is the power and size ( if you take off the cone you can store'em anywhere). They out perform other chippers that take up far more space but offer no more output or capacity. If you would like a testimonial speaking to their toughness...I was clearing brush on my property (the previous owner threw anything back there) And tossed a piece of re-bar that had been mixed into some brush. The unit stopped cold and I was sweating bullets that I had killed it. I opened it up untangled the steel put'er together and it started 1st pull. That was 7 years ago. The support they give you is terrific. Keep the oil changed and the knives sharp and you will have a companion for life. One suggestion: do opt for the electric start on the bigger HP units. It's one of my favorite tools.

This chipper/shredder is so easy to use. It is very portable and moves around the yard with no problems - even uphill. The directions were very well written. They stress to keep the machine in good order regular maintenance is needed, which is no problem. We trimmed branches from 4 mature trees and this machine went right thru them. Best to cut out any stout "Y" branching for ease of getting into chute. The capability of chipping anything up to 3" diameter took care of everything we had to do. The larger branches are going to be firewood. And the chips are now mulch for my backyard plants and hillside. Best money I have spent.

I have a rather overgrown lot, and had been considering a chipper/shredder to help with the debris from clearing it out. I had been considering one of the better known brands, but after reading some unfavourable reviews, and seeing it in person, I decided to do some more research. I found this unit on Amazon, and after looking at the manufacturers website, decided to give it a try. I placed the order through Patriot Products Amazon store, and called the next day to get the shipping details so I could make sure I would be home when it arrived. When I called, I'm pretty sure it was the president of the company that answered. He directed me to the shipping manager, who promptly answered my questions and scheduled delivery so it would arrive on a day that I would be home It arrived just as promised three days later. Great service!

The chipper arrived in perfect condition, and well packaged. There were only a few things that needed to be attached before putting it to use. It took about 10 minutes, and it was time to fill oil and gas and fire it up. Started on the first pull!

I put it to good use over the weekend chipping and shredding bamboo and oak saplings up to about 3". Although it did bog a little with the bigger stuff, if still pulled through and chipped everything I threw at it. Anything smaller than 2"-2.5" didn't even slow it down. It just sucked it in and spit it out!

The unit seems to be well constructed. The unit is constructed out of heavy stamped steel, and it bolted together, rather than pop-riveted like some of the other ones I looked at. Also, the engine is the Briggs and Stratton Vanguard commercial unit, rather than the cheaper 1150 series in the other one I looked at. The only plastic components are the two chutes, but they appear to be of good quality, and are rather thick. I suspect they will hold up quite well. Overall, I am very impressed with this unit.

My wife and I bought this wood chipper because we have two acres of mature landscaping and just could not even keep close to keeping up with trimming the lower branches on all the trees and dispose of the limbs and branches. Our trimming pile at the edge of the woods had grown to a monster and was threatening the back of the garage. Researched several websites and decided on the Patriot.

After the first day of chipping - about 8 hours and 15 trees and lilacs worth of lower limbs and branches, I am impressed. First, the 9HP B&S engine did start on the very first pull. Later in the day on restarts, it sometimes took a twiddle of the choke and at most 3 pulls, but starting was impressively easy, and almost always on the first pull. I limbed about 4 trees at a time, cutting off the biggest stuff for burning in the fireplace, about 2.5 inches or larger. The rest, my wife used large branch clippers to take out ALL Y shaped branch joints (necessary to be able to feed through the funnel tube), and I fed these branches and twigs through the chipper. Very nice!! Blows cleanly into the catcher bag, wich I'd dump into the lawn tractor utility trailer to take to the mulch pile at the edge of the woods. Three loads for the whole day of trimming! Would have been a pile the size of my garage otherwise. On the third bag of chips, we experienced a small jam. Was able to clear by (first unplugging the spark to make sure couldn't start) taking off the funnel feeder (three easily accessible nuts), use a 1" stick on the outlet to back the disk bit by bit and clear the input port of jammed up mulch. I think I must have let the bag overfill, or feed branches with lots of leaves in too fast. Never had a jam afterwards. By the way, those chipping knives are sharp. Be very careful (use only sticks, etc) to clear the openings.

So, we're finished the first day of chipping and am very pleased. This was a pretty spendy unit, but it came through as expected. Very easy to move around the property by hand, even with our hills. No need for the attachment to the lawn tractor, which had the dump bucket attached anyway. I do feel, however, that Patriot should make the tractor attachment a standard item instead of pricey extra!

Would I recommend - you bet. Remember I do not have experience with other chippers, however, but this unit is small and compact but stable, seems to be very powerfull, even on solid dry old branches that have very hard wood, and ate green vines easily if fed into the chipper along with small branches. Nicest part was chipping up some old cedar branches and making cedar wood chips to spread around a couple of trees as mulch. Smells great. Hope this helps your selection. Oh, and seems to be built really solidly, even though this is a small unit. Right as I assembled it (very fast and one spare part of every screw, washer, etc)you could tell that the machine is very solidly made. Happy so far.

This machine does everything as advertised. You should read and follow the instructions on installation and operation, but my machine started on the first pull, and has worked extremely well. As you are working with the unit, watch the bag and be sure to empty it before it is comepletely full.
