Why Patriot?

Why Buy a CSV-2540H

Is this the right model for you?

Our model CSV-2540H is identical to our model CSV-2515 except that it is powered by Honda’s easy starting, quiet running, GX series commercial engine. Like our model CSV-2515, the CSV-2540H is ideally suited for the smaller property owner (up to ¾ acre) whose primary intent is to shred up leaves and other vegetative matter, yet it still has the power to chip up those smaller branches (up to 2 ½ inches in diameter) generated during routine yard maintenance. The CSV-2540H is great for those smaller property owner’s that don’t have easy access to a dedicated electrical circuit or need to work more than 100 feet from an electrical outlet.

Why Buy A Patriot?

Easy to Load Shredding Hopper

Patriot’s CSV-2540H 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’s CSV-2540H 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 Rotor

Now that your yard waste has safely entered our electric wood chipper leaf shredder it meets a formidable opponent, the rotor. Weighing in at just over 13 pounds and measuring roughly 12″ in diameter, this is where things happen!

In this photo you see the front of the rotor and this unit’s one chipping knife (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. Single handedly, this knife can reduce the volume of your freshly pruned branches by as much as 20:1. To sharpen the knife, simply remove the 3 nuts that attach the chipper cone to the housing and the 2 screws that attach the knife to the rotor. Sharpen using a simple wet stone or high quality file.

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 occasional 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.

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 beaten to a pulp. Working together, the y-hammers provide a volume reduction of about 8:1 for leaves.

Commercial Grade Power Source

Since the CSV-2540H is based on the CSV-2515 design, it also needs to be easy to start, light, and run quietly and smoothly. That is why Patriot chose to use Honda’s GX series commercial grade engine. It’s reliability and performance are why it’s the number one choice of rental centers, professional landscapers, and municipal work crews.

Greasable Outboard 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 96 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 discharge 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-2540H – 5 out of 5 stars – Patriot Customer Review – Posted 02/23/23

This product has been extremely dependable and effective. I use it about 4 times a year and it starts up with ease each time and does a great job of shredding smaller branches and acres of Sycamore leaves. I Highly recommend it. If there is anything that can be improved I suggest a stronger/tougher collection bag. I have been through a few, but to be frank I have not compared it to other products on the market and It might well be one of the better ones.

The strongest praise I can offer potential buyers is for the service provided by Patriot. When you pick up the phone there is someone there that genuinely cares about the use and success of their products… not just making a sale. In today’s Amazon culture, thats more than a bonus.

CSV-2540H – 5 out of 5 stars – Patriot Customer Review – Posted 02/22/23

I have never done anything as far as maintenance for our Patriot Chipper and it still starts up quickly and reliably. Since we have been using it for over five years, it does jam more on larger pieces, but I think it just means I finally have to get the blades sharpened. The only thing I would change is to get a larger one. When the time comes we will get another Patriot Chipper.

CSV-2540H – 4 out of 5 stars – Amazon Customer Review – Posted 02/23/15

Arrived in a very secure packing, no issues, Easy to assemble – although a few parts of the instruction could be a little clearer – primarily around the main hopper. Honda engine started on second pull. I have used it with no issues but not five stars yet because I have not really stressed it.

CSV-2540H – 5 out of 5 stars – Amazon Customer Review – Posted 07/31/14

I researched before choosing this model. I didn’t know much about chippers or shredders but I had so many branches down after Hurricane Sandy I had to do something. I love Honda motors, we got a Honda generator too. Very reliable. I am very happy with this choice. Now I want to go get everyone else’s leaves this fall and shred them to use as mulch in my garden!
