(MX-8800-Series) USA 2-pc. Flywheel Knife Set (Reversible Dual Edge) 2013-Current
The WoodMaxx MX-8800 hydrostatic auto-feed chipper is a robust self-feeding PTO wood chipper. This wood chipper is extremely compact, and built to withstand commercial use. The hydrostatic drive system infeed roller pulls material into the chipper head using a powerful, high quality, USA Made hydraulic motor. This motor is powered by the chipper’s self-contained hydrostatic pump and reservoir. Two (2) high quality (A8 tool steel) made in the USA knives are standard equipment on all MX-8800 wood chippers. The design of the WoodMaxx MX-series chipper is so unique and innovative that it is now patented.
WoodMaxx patented MX-series wood chippers are proudly designed, engineered and manufactured in the USA at our Akron NY facility. With a multi-million-dollar investment in the latest high-tech fabricating equipment to increase production, WoodMaxx MX-series wood chippers are in high demand.

POW-R-TORQ™️️ is a trademarked and patented infeed system. This system is a combination of our patented hydro-static pump-motor, specially designed infeed roller, nitrogen filled gas springs, automatic belt tension device and American made A8 tool steel knives. Combined, these features create the most powerful, efficient, and speed variable infeed system available on ANY woodchipper on the market today.
Hydrostatic drive systems have several differences and benefits over traditional hydraulic drive systems. Hydrostatic pumps exhibit variable displacement without the need for external devices such as flow control and flow diverter (proportioning) valves. This reduces the number of fittings, hoses, and amount of oil needed. Unlike hydraulic systems requiring several gallons of oil, our hydrostatic system only needs 2 quarts of motor oil (Why can’t I use synthetic oil in my chipper? Click here to find out.) Hydrostatic technology has been around for decades and is used in some of the highest demanding and harshest mobile applications such bulldozers, trains, excavators, skid steers, and even ride on lawn mowers. Hydrostatic systems are very efficient, generate minimal heat, and are extremely precise, allowing for smooth infeed speed control from 1 ft./min to a full 75 ft./min. with full power through the entire speed range. Take a look below for more information on each of these key POW-R-TORQ™️️ features or watch a short video here.
WoodMaxx MX-series wood chippers are equipped with USA-made hydraulic infeed motors. This high quality 200cc orbital motor offershigh load bearing capacity, giving it the ability to withstand thousands of hours of rotational resistance, that comes with drawing large, dense material into the infeed bin. It also offers extremely high torque for maximum pulling efficiency.
WoodMaxx MX-8800 wood chippers are equipped with a 24″ dynamically balanced flywheel. This flywheel paired with specific engineering components, delivers 200 lbs. of energy to quickly and easily chip a variety of branches. We use a heavy gauge 1/4″ thick (American Standard A-36) structural steel plate to house the flywheel. This features a clam shell design, in which the entire top half of the housing hinges open, allowing for easy access to the flywheel and knives, so knives can be easily changed in as little as 10 minutes.
To allow the flywheel to run extremely true while adding a great deal of strength, the 2″ main shaft on the MX-8800 PTO wood chipper passes through the flywheel housing and is supported by two industrial flange bearings. Competing machines use a 1-3/4″ shaft in conjunction with two pillow block bearings, and the flywheel is cantilevered beyond these bearings. With this setup, there is a possibility of breaking a bearing housing if the machine jams.
WoodMaxx MX-series wood chippers incorporate a series of precisely located ventilation holes in the flywheel chamber. This feature creates a strong vacuum that draws air into the flywheel chamber and in combination with the fan blades on the back of the flywheel forcefully ejects the wood chips out of the chamber. This keeps the discharge chute clear, and reduces the chances of a jam. The WoodMaxx patent pending hole pattern is specifically designed to bring the air into the chamber at the optimal volume and location. Other machines have tried to copy this feature, but have not achieved the same results!
This patented 8.25″ diameter, octagonal shaped, commercial style infeed roller is an innovative design. Specially designed with chisel shaped, spaced teeth, it pulls material into the flywheel at speeds up to 75 ft. /min with ease. The spacing allows the complete down pressure of the high-tension gas springs to be focused on one chisel tooth at a time. This increases total down pressure and allows the roller to self-clean. These rollers, along with the high-tension gas springs aggressively bite into all types of material up to 9″, with or without leaves. Long or short needle pine and small vine type material are no problem for the MX-8800 PTO wood chipper.
WoodMaxx MX-series wood chippers are equipped with five extreme duty 5/8″ wide EDPM rubber cogged drive V-Belts that are made specifically for WoodMaxx. Cogged V-belts run cooler, and transfer more torque than plain smooth V-belts. Although the OEM belts are very high quality, if the need arises, the standard size BX belts allows you to purchase replacement v-belts at any auto parts store.
The hydraulic hose configuration for the WoodMaxx MX-8800 requires only two streamlined hydraulic hoses. Because of the POW-R-TORQ™ infeed system, we’re able to eliminate many of the components and hoses, traditional open hydraulic systems have. We also utilize standard JIC (joint industrial council) hose fittings that are rated for 5000 psi, so should you need to replace a hydraulic hose, maintenance will be effortless, and parts are easy to find.
The WoodMaxx MX-8800 wood chipper offers a large 24″ Wide x 20″ tall infeed opening that funnels down to 8″x 8″ to easily accept those crooked branches.
Safety is paramount on WoodMaxx wood chippers. Located on the top of the infeed bin, the MX-8800 utilizes an easy to activate hydrostatic auto-feed stop safety bar to disengage the infeed roller in case of an emergency, or to clear the infeed bin if necessary. Simply pull the bar forward to increase the speed and push it forward to decrease or reverse the infeed speed and direction. The hydrostatic drive system is so refined that the infeed speed is fully adjustable from 0-75 ft./min.
The WoodMaxx MX-8800 PTO wood chipper is equipped with a 360 degree swivel discharge chute. With easy one-handed operation, we have incorporated a convenient handle that effortlessly allows you to swivel the discharge chute 360 degrees so that you can direct the chips into a trailer or the back of a pickup truck without having to move the entire machine. Simply push down on the handle and swing the chute, when you release the handle a spring-loaded pin drops down to lock the chute into position. No tools required.
The WoodMaxx MX-series wood chipper utilizes USA made high tension gas shock. These gas shocks maintain the same tension throughout the entire range of motion. This feature also slows and dampens the downward motion of the infeed roller to prevent the infeed roller from slamming downward, ultimately increasing the longevity of the components. These high-tension gas shocks achieve 185 lbs. of downward force that allows the teeth of the infeed roller to dig into the branches and ensure a smooth entry into the chipper head.
The hydrostatic pump belt tensioner is automatic on the MX-8800 wood chipper. This feature keeps consistent and correct pressure on the drive belt. If the drive belt is too tight then excessive bearing and or pump failure is likely. If it’s too loose, the belt will slip. This feature eliminates the need to adjust the belt, ensures that proper tension is achieved, and increases the longevity of the pump and bearings. It also saves you the hassle of constant adjustment.
The WoodMaxx MX-8800 wood chipper is equipped with four USA made and offset, reversible dual edge knives, so that with every 90 degrees of rotation, the knife is taking a slightly different cut of material. This is equivalent to using a serrated knife to cut bread instead of a straight knife. These knives are attached to the flywheel. Ultimately, this feature allows for chipping large material without overworking your tractor. The reversible knives means that you get twice the work out of one set! Designed for extreme-duty – there is no better material than A-8 hardened tool steel for superior performance and life. Click here to learn how long your chipper knives will last.
WoodMaxx MX-series wood chippers are now equipped with a convenient tachometer/ hour meter. The tachometer allows the operator to see the actual RPM of the flywheel to ensure that the chipping head is running at the optimal recommended speed. Proper flywheel speed is important to develop the inertia required to chip hard material and evacuate the chamber effectively. The hour meter is helpful to ensure that proper maintenance intervals are kept in accordance with WoodMaxx recommendations. This all-weather meter is water proof and weather tight.
MX-series PTO wood chippers will mount to any Category 1 or 2 three-point hitch attachment and is category 1 quick hitch ready.
NOTE: A shear bolt torque limited 29” Premium PTO shaft is included with the purchase of any WoodMaxx MX-series wood chipper. Shear bolts are replaceable with a 5/16-18″x 1 1/4″ grade 5 Hex bolt that is readily available at any hardware store.

Chipper construction: 5 stars.
Simple design, effective, easy to service. Well-balanced.
I had to make an extension for the top link, since the ram wouldn’t reach.
Chipper Action: 4 stars.
The infeed roller allows the 8″ feed hole to open completely. The roller sometimes slips on certain branches, even when the cutting blades are sharp (the cutters do part of the pulling), or sometimes can’t climb larger ones. Feed speed is variable, so even an underpowered drive unit can tackle large items by slowing the feed speed. I have 19hp at the PTO, and this has worked fine.
Customer service: 5 stars.
Service has been excellent, with prompt responses and even supplying a rather large part for free in order to rectify an alignment problem.
Suggestions when you shop:
After several years of use, I would look for the following:
* Get the biggest infeed opening you can afford. My biggest difficulty is trying to feed oak branches with twists and turns that block their entry into the chipper, forcing me to back it out and cut the offending branch so it’ll fit. Pines need to have branches trimmed off. The bigger the hole, the less time-consuming-trimming is necessary. With variable infeed speed, power is less important, since you can slow feed speed and prevent stalling.
* A small tilt of the chute would allow loose pieces to migrate to the roller/cutter.
* The larger the diameter of the infeed roller, the more easily it will roll over and pull in large pieces.
In other words, think big! Overall, the MX8800 is a very good unit.
I bought this machine thinking it would not live up to my expectations; I was fully prepared to buy it and sell it again.
We do trees and landscaping commercially – we use this chipper for 8+ hours a day several days a week on average.
Aside from the flywheel getting out of balance a couple times, this chipper has been flawless. With sharp knives, it’ll eat 8″ hardwood (just not a full speed). We fill a 7x14x4 dump trailer a day with chips from brush all the way up to 8″ logs.
Great machine, great price. I thought having a chipper on a tractor (John Deere 3039R) would be too cumbersome to use, but having a mobile chipper has been a huge plus.
Would buy again happily.
First of all if you are reading this you should know, professionals would think I was small time, but many would be impressed.
As a result of living on the left coast, large fines are levied for completing the carbon cycle (I do not fall into the miss manage and then let as much as you would like burn category). Henceforth, in comes the MX-8800.
I have approximately 5 hours on this unit. So far it is fantastic, and I am confident it will remain so. Mine is attached to 3046R John Deere, this combination works very well with no complaints from either end.
This machine has chewed through everything I could feed through the hopper without issue, hard and soft wood alike.
Like most I trade my time for money, and my money for time. This unit and the hydrostatic infeed is worth it.
A pleasant surprise came while unpacking the unit. My 10 year old who is very active in our processes, discovered the card signed by the employees that had built it. I was glad for the opportunity to explain to him, that this was the reason I had researched and decided on this unit. Americans taking pride in their work and producing quality, is why I was willing to invest a little more of my hard earned money on this product. We all won that night.
It is refreshing to buy a quality piece of equipment, not compromised in any way. It does everything they say it will do and is backed up with superior service. I can’t recommend the product, an MX8800, or the company any higher.
Great machine! Hydrostatic infeed works amazingly well, and machine overall is excellent. Love the fact it’s US sourced.
