(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 hydrostatic 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 wood chipper 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.
The WoodMaxx MX-8800 requires a tractor with a category 1 or 2 three-point hitch and at least 20 HP at the PTO. Chipping capacity is directly related to horsepower and torque, therefore with 20 HP you can expect to chip 4″ hard wood and 6″ soft wood. With 50+ HP you can expect to chip any material up to 8″ in diameter with no trouble.
The WoodMaxx MX-8800 wood chipper is equipped with a USA-made hydraulic infeed motor. This high quality 200cc orbital motor offers high 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 high tension gas springs. These gas springs 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 springs force 175 lbs. of downward pressure 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 two 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.
