(WM-Series) USA 2-pc. Flywheel Knife Set (Reversible Dual Edge) 2013-Current
The WoodMaxx WM-8M mechanical 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. 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.
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.
Another WoodMaxx exclusive! Designed by WoodMaxx, copied by some. 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 in-feed roller: the overall diameter, blade spacing, tooth angle, type of steel, hardness, down pressure and speed. After countless hours of R&D on the in-feed system, we have developed a large diameter (6.25″) in-feed roller that easily climbs up and grabs the branches to bite in and efficiently pull the material into the flywheel at up to 58 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 wood chippers utilize in-feed rollers with high carbon steel chisel teeth. This type of in-feed 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 in-feed rollers is a feature that should not be overlooked when shopping for a wood chipper. Our in-feed roller designs are so effective and unique that we now have patents pending.
The infeed system on the WM-8M utilizes a belt driven oil bath heavy duty gear box that increases torque and transfers power to the upper feed roller through an extreme duty drive axle. For long life, the drive axle is machined splined (similar to the PTO spline of your tractor), and the U-joints are protected from debris by a rubber boot. The clutch mechanism is precisely machined from solid steel to ensure proper function. This in-feed system will feed material at a rate of 58 ft./min.
All WoodMaxx WM-series chippers are now category 1 quick hitch compatible. WoodMaxx is the only PTO chipper that works with quick hitch (**John Deere I-match/Land Pride QH10 & QH05require 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 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)
360 degrees of rotation and 2 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.
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.
WoodMaxx WM-series wood chipper attachments 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!
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.
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.
WoodMaxx WM-series chippers use heavy gauge 8mm 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.
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.
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 15mm belts – try to find those in the USA!
Safety is paramount on WoodMaxx chippers. Located on the top of the in-feed bin, the WoodMaxx 8″ PTO chipper utilizes an easy to activate auto-feed stop safety bar to disengage the in-feed rollers in case of an emergency, or to clear the in-feed bin if necessary. This safety bar can be actuated and left in the off position, hands free, so that the operator can use both hands to clear the in-feed bin. This feature is safer because it allows the user to start the chipper without the feed rollers turning. Other chippers require a hand on the safety bar to keep the feed rollers in the off position.
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 in-feed ability.
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.
WoodMaxx chippers come shipped to you in a steel crate and are almost completely assembled. Simply attach the in-feed bin, discharge chute, PTO shaft (included), and attach to your tractor. All WoodMaxx chippers are given a comprehensive 22 point inspection, and are serviced prior to leaving our warehouse. The drive belts have been aligned and tightened, knives have been installed, adjusted, and torqued down, and bearings have been greased. These and other steps performed here greatly reduce assembly time on your end. Just follow the illustrated, American written, user friendly assembly manual (and watch the video), and you will be up and running in about 2 hours.
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 PTO wood chippers are able to accommodate tractors that have a PTO height from 18″ to 30″ high.
The 2″ main shaft on the WM-series PTO wood chippers 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.
WM-8M… 950lbs (shipping) Steel crate dimentions are L=46″ x W=36″ x H=48″
More weight = more steel
More strength and stability… period.
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.
The infeed hopper on the WM-series wood chippers is horizontal and approximately table height for easy material loading.
The powder coat finish is baked on at 450 degrees, and is thicker and more durable than ordinary paint.
