WM-8H Wood Chipper
The WoodMaxx WM-8H hydraulic auto-feed chipper is a robust self-feeding PTO driven wood chipper attachment that mounts to the 3-point hitch of your tractor. This PTO wood chipper is compact, yet built to withstand commercial use. Dual powered infeed rollers grab and pull material into the chipper head using two powerful hydraulic motors. These motors are powered by the chipper's self-contained hydraulic pump and tank. High quality made in the USA knives are standard equipment on all WM-series wood chippers. The WoodMaxx WM-series chippers are so unique and innovative that they are now patent pending. Attempts have been made to copy this machine, but there is only one WoodMaxx! Check out these features.

WM-8H FEATURES INCLUDE:
STRENGTH IN DESIGN
WoodMaxx WM-series 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. WM-series chippers are loaded with features typically found on much larger commercial machines that are much more expensive. The strength of our machines start with using heavy formed Q-235 (American standard A-36) structural steel plate; the strongest plate steel available. Each piece is CNC plasma cut, and meticulously welded. WoodMaxx WM-series chipper exclusive structural design includes a 2" diameter main shaft that passes through the flywheel housing and is supported by 3 bearings: 1 pillow block and 2 flange bearings. This feature, combined with the 2" shaft, allows the flywheel to run true and ads 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.
The WoodMaxx WM-8H requires a tractor with a category 1 or 2 three point hitch and at least 19 hp. at the PTO. Of course chipping capacity is directly related to horse power and torque, therefore with 19 hp. you can expect to chip 4" hard and 6" soft material and with 50 hp. you can expect to chip any material up to 8" in diameter with no trouble. In testing a 30 hp. tractor gave excellent work to fuel consumption results. Tractors with more than 50 hp. will not over power or damage the wood chipper since it is shear bolt protected, but will simply consume more fuel to accomplish the same results.
TRUE 8" x 8" INFEED OPENING
WoodMaxx WM-series wood chippers offer a larger 8"x 8" infeed to easily accept those crooked branches. Other 8" chippers open 8" wide, but only 4-1/2" high.
200 LBS FLYWHEEL - IDEAL WEIGHT
WoodMaxx WM-series chippers use a 24" dynamically computer balanced 200 lbs. flywheel to run smooth and deliver the energy to 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 lbs. flywheel is ideal for this size of wood chipper.
MADE-IN-USA CHIPPER KNIVES
WoodMaxx WM-series wood chippers are equipped with made in USA 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 life and performance than our heat treated, through hardened, high carbon, high chromium, A-8 tool steel knives.
DUAL EDGE REVERSIBLE CHIPPER KNIVES
WoodMaxx WM-series wood chippers come standard with reversible dual edge knives installed. This means you get twice the work out of one set of knives! These knives are bolted into a milled pocket in the flywheel, incorporating a new flywheel pocket design developed at WoodMaxx. Unlike most other reversible knives, which are only held on by bolts, the flywheel on the WM-series chipper was redesigned to actually help to hold the knives on. This eliminates knife and bolt breakage that can be found on other dual edge knife systems. And, as always, these knives are made right in the USA of hardened, high carbon A-8 tool steel, right here in upstate New York. Click here to learn how long your chipper knives will last.
WoodMaxx WM-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.
SELF CONTAINED HYDRAULICS
WoodMaxx WM-8H chippers are complete with a self-contained hydraulic pump and a 38L (7) gallon reservoir tank to power the two infeed motors. Hydraulics are not required from your tractor. Hydraulic motors are 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 19 horsepower at the PTO to operate this machine.
JIC STANDARD HOSE FITTINGS
The WoodMaxx WM-8H wood chipper utilizes JIC (joint industrial council) hose fittings and hoses 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.
SLEEK HYDRAULIC HOSE CONFIGURATION
The hydraulic hose configuration for the WM-8H has been streamlined to eliminate the possibility of snagging a hose and offers a sleek new look.
NYLON PROTECTIVE HYDRAULIC HOSE WRAP
Along with the new hose configuration, the WM-8H now includes the additional protection of nylon hydraulic hose wrap for long life. This hose wrap reduces chaffing and protects the hoses from environmental damage.
PRESSURE COMPENSATION FLOW CONTROL VALVE
The addition of this valve allows for very precise infeed roller speed without causing back pressure on the hydraulic pump. This allows the user to regulate the speed of the infeed rollers to exactly match their tractors capabilities while increasing the life of the hydraulic pump.
VARIABLE SPEED DUAL HYDRAULIC INFEED MOTORS
Variable speed (10-75 ft./min) aggressive dual counter-rotating hydraulic powered infeed rollers work together to pull material into the chipper head. This feature allows the user to slow the infeed speed down to accept large material.
6.25" DIAMETER HARDENED STEEL COMMERCIAL STYLE INFEED ROLLERS -
Another WoodMaxx exclusive! Designed by WoodMaxx, copied by others. We all know what happens to the branches when they reach the flywheel, but getting the material to pull into the chippers quickly and effectively is the trick. Many factors come into play when designing an effective infeed roller: the overall diameter, blade spacing, tooth angle, type of steel, hardness, down pressure and speed. After countless hours of research and development on the infeed system, we have developed a large diameter (6.25") infeed roller that easily climbs up and grabs the branches to bite in and efficiently pull the material into the flywheel at up to 75 ft./min. 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. We equate this to the small wheels of a shopping cart stopping when it contacts a small stone in the parking lot. WoodMaxx auto feed chippers utilize infeed rollers with high carbon steel chisel teeth. This type of infeed roller is found on larger, much more expensive machines.
We have also spaced the teeth out to prevent material like leaves and bark from getting impacted between the teeth. This allows the roller to self-clean, and also allows the 165 lbs. of down pressure to focus on fewer teeth which increases the bite. These rollers, along with the high tension springs aggressively bite into any type of material. After welding, these rollers are induction 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 up to 8" with or without leaves. Small, vine type material as well as long or short needle pine is no problem for the WoodMaxx WM series chipper. Vines, leaves, and small branches won't
wrap around the roller as they would on other chippers. The 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 effective
and unique that we now have patents pending.
QUICK HITCH READY -
All WoodMaxx WM-series chippers are category 1 quick hitch compatible. WoodMaxx is the only PTO chipper that works with quick hitch (**John Deere I-match/Land Pride QH10 require a special top link that we make for this purpose, please call to specify if you need this). Save time by never leaving the seat of your tractor to link up with the WM-series wood chipper. Attaching the chipper to your quick hitch takes only seconds. Please note, you'll need the Premium PTO shaft or a longer imported PTO shaft if you have a quick hitch (contact us for more info). Check out our video tab to see the quick hitch in action! No quick hitch? No problem. The chipper will easily attach to a standard 3pt hitch, just back in and insert the pins. No need to force the draw arms of your tractor around the draw pins (as with many other implements).
EASY SWIVEL DISCHARGE CHUTE
360 degrees of rotation and two finger operation. We have incorporated a convenient handle that effortlessly allows you to swivel the discharge chute so that you can direct the chips into the back of a truck or trailer 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.
WIDE FOOTPRINT SKID TYPE SUPPORT BASE
Because of its robust weight and to prevent the machine from sinking into the soft ground during operation, the new WM-8H offers a wide footprint skid type support base. This base is angled upward on the end to prevent digging into the ground while transporting.
AUTOMATIC BELT TENSIONER -
The automatic belt tensioner on the WM-8H hydraulic pump drive belt keeps consistent pressure on the belt. If the drive belt is too tight then excessive bearing and or pump failure is likely, too loose and 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. Also saves you the hassle of constant adjustment.
ADJUSTABLE BASE LEGS
You asked for it and we delivered! In 2012 WoodMaxx developed the first adjustable chipper base legs. These adjustable legs will help accommodate a larger variety of tractors. This innovation allows you to more easily meet the required PTO shaft angle (less than 15 degrees) on larger tractors. Simply insert the adjustable legs, and then slide the pin into the hole for your required leg height. WoodMaxx wood chippers are able to accommodate tractors that have a PTO height from 18" to 30" high.
HIGH FLOW FLYWHEEL CHAMBER VENTILATION -
WoodMaxx WM-series PTO 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 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!
HEAVY DUTY CAST STEEL BEARING HOUSING
Three heavy duty cast steel bearings support the main shaft, which passes through the flywheel housing, and is supported on either side by flange bearings. This heavy duty, shock resistant cast steel bearings are much more durable than cast iron - a unique feature of the WoodMaxx chipper.
MAIN SHAFT SUPPORTED BY THREE (3) BEARINGS
The 2" main shaft on the WM-series wood chipper passes through the flywheel housing and is supported by 1 pillow block and 2 flange bearings. This feature, combined with the 2" shaft, allows the flywheel to run truer, and adds a great deal of strength. Other chippers use a 1-3/4" shaft, 2 pillow block bearings, and the flywheel is cantilevered beyond the bearing. With this setup, there is a possibility of breaking a bearing housing the machine jams.
FULLY ADJUSTABLE INFEED ROLLER TENSION SPRINGS
The WoodMaxx WM-series chipper utilizes high tension springs in conjunction with a unique adjustment mechanism that offers a full range of variable down pressure, since all branches are different - some soft and some hard. This feature allows the user to increase to decrease the upper roller down pressure to suit the situation. Crank up the tension to achieve up to 165 lbs. of down pressure. This allows the teeth on the roller to dig into the branches and ensure a smooth entry into the chipper head.
WM-8H... 990 lbs. (shipping) steel shipping crate L=46" x W=36" x H=48"
More weight = more steel
More strength and stability... period.
8mm THICK FLYWHEEL HOUSING
WoodMaxx WM-series wood chippers use heavy gauge 8 MM thick Q235 (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. Other chippers use only 1/4" steel.
EASY KNIFE ACCESS PANELS
WoodMaxx WM-series chipper knives can be changed from the side of the machine by one person in as little as 10 minutes. 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.
ADJUSTABLE BED [ ANVIL ] KNIFE
WoodMaxx WM-series wood chippers are equipped with an adjustable bed knife to ensure that the proper knife gap is achieved. This feature allows the user to adjust the distance between the flywheel knife and the bed knife so that the required distance is maintained after knife sharpening. Proper gap is important so that even the smallest material is chipped as it passes through the chipper.
HEAVY DUTY 5/8" COGGED DRIVE V-BELTS
WoodMaxx WM-series chippers are equipped with extreme duty 5/8" wide cogged drive v-belts. 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 BX size allows you to purchase replacement v-belts at any auto parts store. Other chippers use 15 mm belts - try to find those in the USA!
SAFETY AUTO FEED STOP BAR
Safety is paramount on WoodMaxx chippers. Located on the top of the infeed bin, the WM-8H utilizes an easy to activate hydraulic auto-feed stop safety bar to disengage the infeed rollers in case of an emergency, or to clear the infeed bin if necessary. By simply pulling down on the bar, the user can stop and even reverses the direction of the infeed rollers.
HANDY FEED ROLLER ASSIST HANDLE LOCATED ON TOP OF MACHINE
This feature allows the user to access the handle from either side of the machine. The center lift point allows the WM-series chipper to use stronger tension springs, increasing the infeed ability.
HORIZONTAL INFEED HOPPER
The infeed hopper on the WM-series wood chippers is horizontal and approximately table height for easy material loading.
RUST RESISTANT POWDER COAT
The powder coat finish is baked on at 450 degrees, and is thicker and more durable than ordinary paint.
CLEAR VINYL BAFFLE
The clear vinyl baffle feature protects the user from chip blow-back, while allowing the user to see what is going on in the hopper.
3 YEAR WARRANTY
This robust chipper comes with an equally robust 3 year warranty. Our service department also stocks a full line of replacement parts.
WoodMaxx wood chippers include a standard PTO shaft, but for an additional $135.00 upgrade charge, we do offer a very high quality Premium PTO shaft. The Premium shaft retails for $250 if purchased separately from the machine. Have a quick hitch? The Premium shaft is compatible, or ask about our longer imported PTO shaft.
