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 will grab and pull material into the chipper head using a powerful hydrostatic pump & motor combination. The hydraulic motor is powered by the chippers’ self-contained hydrostatic pump and reservoir. 2-High quality (A8 tool steel) made in the USA knives are standard equipment on all MX-series wood chippers. The design of the WoodMaxx™ MX-series chipper is so unique and innovative that it is now patent pending.


WoodMaxx™ MX-8800 wood chipper comes shipped to you in in a wooden crate and is 95% completely assembled. Simply attach the MX-8800 wood chipper to your tractor, attach the infeed bin, raise the discharge chute, size and attach the PTO shaft (included), and fill the oil reservoir with 2 quarts of 10-W40 motor oil. The WoodMaxx™ MX-8800 wood chippers are manufactured and assembled right here at our facility and are given a comprehensive 22-point inspection, and are serviced prior to leaving our warehouse. Simply follow the user-friendly operator manual and you will be chipping in no time at all.


WoodMaxx™ MX-8800 wood chippers use a 24.5" dynamically balanced 200 pound flywheel to deliver the energy to quickly and easily chip all types of material. Competitors use a wide range of flywheel weights, but through thorough testing and experimentation, WoodMaxx™ has discovered that the 200 pound 24.5” flywheel is ideal for this size wood chipper .


All WoodMaxx™ MX-series wood chippers are equipped with made in USA chipper knives and made in USA Holo-Krome class 12.9 knife bolts. Designed for extreme duty – there is no better material that can be used for superior performance and life than our through hardened, heat treated, high chromium, high carbon, A-8 tool steel knives.


The WoodMaxx™ MX-8800 wood chipper comes standard with two reversible dual edge knives installed. The reversible knives mean that you get twice the work out of one set of knives! These knives are securely bolted into a pocket that is milled in the flywheel using American made Holo-Krome bolts for added security, this design utilizing a new flywheel pocket design developed by WoodMaxx™. This eliminates knife and bolt breakage that can be found on other dual edge knife systems. WoodMaxx chipper knives are made right here in upstate New York of hardened, high carbon A-8 tool steel. Designed for extreme duty – there is no better material that can be used for superior performance and life than our through hardened, heat treated, high chromium, high carbon, A-8 tool steel knives.


Patent pending design the WoodMaxx™ MX-8800 wood chippers are complete with a self-contained hydrostatic pump that requires only a two quart oil reservoir tank to power the infeed motor. Unlike a standard hydraulic system, a hydrostatic drive system is so powerful that it is the same type of drives system that is used to drive bulldozers, trains, excavators, skid steers, and even ride on lawn mowers. These hydrostatic systems use standard 10W-40 motor oil, a spin on oil filter and are so efficient, generate so little heat, that they require only a fraction of the reserve oil as a standard hydraulic drive system. This type of system also allows for complete speed control from 1 RPM to a full 75 ft./min. with full power through the entire speed range. The Hydro-static drive system on the WoodMaxx™ MX-8800 is so unique to the industry that it is now Patent Pending. Hydraulic remotes are not required from your tractor. The hydrostatic motor is a standard SAE 2 hole “A” mount. What does this mean to you? Down the road if there is a need to replace the motor, it can be found just about anywhere. Please note, you will need at least 20 horsepower at the PTO to operate this machine.


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.


WoodMaxx™ MX-series wood chippers are equipped with USA “White drive products” brand hydraulic infeed motors. White is renowned for their high-quality American engineered hydraulic motors.


The WoodMaxx™ MX-8800 PTO Wood chipper attachment is equipped with a comfortable table height infeed bin. This allows the user ergonomic feeding of material.


The WoodMaxx™ MX-8800 wood chipper offers a large 8”x 8” infeed opening to easily accept those crooked branches. This is the largest infeed opening available of any PTO wood chipper in its class.


The WoodMaxx™ MX-8800 PTO wood chipper is manufactured using heavy gauge 1/4” thick (American Standard A-36) structural steel plate for the flywheel housing. Since the flange bearings are mounted on the flywheel housing, this gives added strength and rigidity.


WoodMaxx™ MX-series wood chipper knives can be changed easily by one person in as little as 10 minutes. The entire top of the blower housing opens like a clam shell. This allows for easy access to the flywheel and knife changing. Other chippers require you to reach into the infeed bin to hold the head of the bolt, while someone else turns the nut from the backside of the flywheel


WoodMaxx™ MX-series wood chippers are equipped with five extreme duty 5/8” wide 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. Other chippers use 15mm belts—try to find those in the USA!


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 in-feed speed and direction. The hydrostatic drive system is so refined that the in-feed speed is fully adjustable from 0-75 ft./min.


WoodMaxx™ MX-8800 wood chippers are the perfect combination of size, weight, and features. Compact enough to easily move around, yet strong enough to get the tough jobs done. MX-series chippers are loaded with features typically found on much larger commercial machines that are much more expensive. The strength of our machines starts with using heavy formed (American standard A-36) structural steel plate, the strongest plate steel available. Each piece is laser cut, on a precision CO2 laser and meticulously welded by highly skilled American welders. WoodMaxx™ MX-series chipper exclusive structural design includes a 2” diameter main shaft that passes through the flywheel housing and is supported by two flange bearings. This feature, combined with the 2” shaft, allows the flywheel to run true and adds a great deal of strength. This design sets WoodMaxx™ chippers far apart from the competition, and it is a design feature you should not overlook when shopping for a chipper.


WoodMaxx™ MX-8800 wood chippers are extremely robust, and can handle very heavy use. Designed and manufactured in upstate New York, each machine we offer is thoroughly tested on our 18 acre proving grounds before being offered to the public. With years of experience and thousands of machines in service today, we are confident that this machine can handle even the toughest projects that you have. Our machines are currently in service in several commercial applications, such as: the Army Corps of Engineers, college campuses, municipalities, tree farms, golf courses, apartment complexes, and thousands of residences. WoodMaxx™ chippers are also represented around the globe, with machines as far away as Hawaii, and Alaska, as well as several countries including: Chile, Russia, Panama, Colombia, Poland, United Arab Emirates, Israel, west Africa, Greece, Norway, Iceland, Ecuador, Honduras, Ireland and of course Canada.


A WoodMaxx™ exclusive and patent pending design. Everyone knows what happens to the branches when they reach the flywheel knives of the wood chipper, but getting the material to pull into the wood chippers effectively and quickly is the trick. Many factors must be considered when designing an effective infeed roller system: the overall diameter, knife spacing, tooth angle, type of steel, hardness, down pressure and infeed speed. After countless hours of research and development on the infeed system, for the MX-8800 we have developed a large diameter (8”) infeed roller. This exclusive design allows the chisel shaped teeth of the roller to grab and climb up and over the branches to easily bite in and effectively pull the material into the wood chipper flywheel at speeds up to 75 ft. /min. In short, the larger the roller, the easier it rolls over the material. The smaller the roller, the more likely it is to slip and spin on the branches. Similar to how the small wheels of a shopping cart stop when contacting a small stone in a parking lot. WoodMaxx™ MX-series auto-feed wood chippers utilize high carbon steel chisel tooth infeed rollers. This type of infeed roller is typically found on much larger, much more expensive commercial machines.

To prevent material like tree bark and leaves from impacting between the teeth of the infeed roller, we spaced the chisel teeth out. This spacing allows the complete down pressure of the high-tension gas springs to be focused on one chisel tooth at a time increasing total down pressure. Additionally, this spacing allows the roller to self-clean. These rollers, along with the high-tension gas springs aggressively bite into any type of material. After welding, these rollers are hardened to ensure that the teeth stay sharp for many years to come. The advantage of this type of roller is that is aggressively grabs any size limb with or without leaves up to 8”. Long or short needle pine, as well as small, vine type material is no problem for the WoodMaxx™ MX-8800 wood chipper. Small branches, leaves, or vines won’t wrap around the infeed roller as they would on other wood chippers. The exclusive advanced design of our infeed rollers is a feature that should not be overlooked when shopping for a wood chipper. Our infeed roller designs are so unique and effective that they are now patent pending.


The WoodMaxx™ MX-8800 PTO wood chipper is equipped with a 360 degree swivel discharge chute. With easy two finger 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 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.


Because of the extreme weight of this chipper, we have provided for a wide footprint base that distributes the weight of the chipper over a larger area to prevent it from sinking into soft ground during operation.


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!


The WoodMaxx™ MX-8800 wood chipper utilizes JIC (joint industrial council) hose fittings that are rated for 5000 psi. For you this means that if you ever need to replace a hydraulic hose, that your local tractor supply or auto parts store can make hoses while you wait. JIC fittings are widely used in hydraulic fluid transfer, the military, and are typically very easy to come by. No trying to chase down an adapter because of mismatched threads.


The 2” main shaft on the MX-8800 PTO wood chipper passes through the flywheel housing and is supported by two industrial flange bearings. This feature, combined with the 2” shaft, allows the flywheel to run extremely true, while adding a great deal of strength. Competing machines use a 1-3/4” shaft in conjunction with two pillow block bearings, and the flywheel is cantilevered beyond these bearing. With this setup, there is a possibility of breaking a bearing housing if the machine jams.


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 achieve 175 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.


MX-8800…850lbs of American made steel!


The WoodMaxx™ MX-8800 is finished with a powder coating that is baked on at 450 degrees. Powder coating finish is thicker and more durable than ordinary paint. Additionally, prior to powder coating the steel is prepared by shot blasting, (similar to sand blasting but with steel shot instead) which slightly scuffs and textures the steel to provide for a superior bonding surface. This is a more costly process but is superior to simply chemically cleaning the steel as most other will do.


Safety is paramount, therefore the WoodMaxx™ MX-8800 is equipped with a clear vinyl baffle feature that protects the user from chip blow-back, while allowing the user to see what is going on in the hopper.


The hydraulic hose configuration for the WoodMaxx™ Mx-9900 requires only two streamlined hydraulic hoses. This is possible because of the patent pending upgraded hydrostatic drive system that eliminates many of the components and hoses of traditional open hydraulic systems. This feature makes future maintenance a breeze.


Along with the simple two hose configuration, the MX-8800 includes the additional protection of nylon hydraulic hose wrap for long life. This hose wrap reduces chaffing and protects the hoses from abrasion and environmental damages.


The WoodMaxx™ MX-8800 wood chipper comes with a standard imported PTO shaft. For an additional $150 you can upgrade to a premium quality USA made PTO shaft if purchasing with the chipper. When purchased separately, the USA PTO shaft will be $250. Have a quick hitch? The USA PTO shaft is compatible, or ask about our longer imported PTO shaft

Reviewer: SHAUN ADAMS from BANDERA, TX United States  
I bought the chipper to clean up our family ranch and was very apprehensive about spending this much money but I needed something durable that was going to get used quite a bit. I have had it over a month now and have really put it to the test. This thing is a BEAST, I seriously cant believe how well it works. I would say I have about 20 hrs hard use give or take and it hasn't slowed down a bit. Knives still seem sharp as the chips are really nice. Soft stuff like cedar, hard stuff like dead dried up oak, doesn't care. You can tilt the deflector all the way up and spray the chips all over for coverage or tilt it down and have a pile at your feet in no time. I am extremely pleased with my purchase and would recommend it to anyone.  Used on a JD 4044m with 35 pto hp which is plenty. Stop thinking and just buy it already.

MX8800 Chipper April 27, 2017
Reviewer: Terry from Covington, GA United States  
I got my chipper about a month back but due to schedule just have had a chance to test it. I had several large limbs and a tree top that came down earlier this year. they were dried out and hard. Most were about 2 inches they went through with no problem. I had a tree top that was about 6 inches. I decided to put it to the test. I slowed the roller down and put the top in. The roller grabbed it. The tractor did slow a little but the chipper was able to handle it no problem. It should handle the area I am going to clear with no problem. The assembly was no problem. I did get my wife to hold some of the panels till I got the bolts started. I did have a small leak in the Hydrostatic hose I tightened the connect will check again after I use it more..I am using a 1987 Massey Ferguson 240 tractor. PTO is rated 37 to 41 horse power.

Bulldog April 24, 2017
Reviewer: James Brogger from Lenoir City , TN United States  
Final assembly is straightforward. Put to work two days after delivery. Ate everything I fed into it with ease. Extremely pleased with this purchase. Only complaint is the manual. Lubrication is recommended every 10 hours; would have been nice to have a diagram showing the grease fittings. (WoodMaxx response, we will update the manual to show location of the grease fittings, thanks for the feedback)

Wow. April 4, 2017
Reviewer: D. Spalding from St Albans, ME United States  
Chipper arrived yesterday. (Driver insisted I open it, not because it looked damaged, but because he wanted to get a look at it). I started to unpack it late in the day and decided it was better to leave it until this morning. Wow. I didn’t have the courage to even imagine the 8800 would actually work as described and advertised. Great work on the part of the engineers there. The heavy steel construction makes it vibration-free and it does indeed haul fir tops right in as I'd hoped it might. So far I've run stuff up to 4 inches in diameter just to work up my nerve running it. The speed it takes the wood through is just right for a one-person operation, without worrying that the tractor is running with nothing to do.

I would recommend it September 6, 2016
Reviewer: DON G. from ESTANCIA, NM United States  
The chipper was quite simple to assemble and check out. At start-up nothing was loose and there was no banging, etc.  The chipper was really smooth. I have about 3,000 trees to process. The MX-8800 has been used for almost 4 hours now and it has performed perfectly.  The output is exactly as I expected and the chips will be perfect for retaining rain water and shielding seeds for regrowth of our burned area.  Throws chips as specified and the 360 degree rotation of the chipper output makes it convenient to spread the chips. I am chipping dry, burned Pinion and Juniper trees and they are not quite as easy as recently cut trees, but the chipper has taken up to a 5” tree trunk. I have a hard time keeping up with the feeder giving it 3” and down limbs.  I have used other chippers including Vermeer commercial units.  The performance of this unit is perfect and when you compare it to the price of the competition you will certainly find that the value is there.
