WM-8M MECHANICAL AUTO FEED CHIPPER...
The WoodMaxx WM-8M mechanical auto-feed wood 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 rigorous use. Dual infeed rollers grab and pull material into the chipper head using a sturdy belt driven gear box and drive axle system. High quality (A8 tool steel) made in the U.S.A. chipper knives are standard equipment on all WM-series wood chippers. Check out these features. The WoodMaxx WM-series chippers are so unique and innovate 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-8M FEATURES INCLUDE:
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.
WoodMaxx WM-8M requires a tractor with a category 1 or 2 three point hitch and
at least 19 hp. at the PTO up to 100 hp. 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 overpower and damage the wood chipper since it is shear
bolt protected, but are simply going to burn more fuel to accomplish the same
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"
200 LBS FLYWHEEL - IDEAL WEIGHT
WoodMaxx WM-series chippers use a 24"
dynamically computer balanced 200lbs
flywheel to deliver the energy to deftly chip all types of
material. Competitors use a wide range of flywheel weights, but through
thorough testing and experimentation, WoodMaxx has discovered that the 200lbs
flywheel is ideal for this size wood chipper.
IN USA KNIVES
All WoodMaxx WM-series 3 pt. hitch mounted wood chippers are
equipped with made in USA knives and made in USA Holo-Krome class 12.9 knife
bolts. These types of wood chippers are 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 wood 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.
TACHOMETER/ HOUR METER - NEW FOR 2016
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 logs 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.
6.25 DIAMETER HARDENED STEEL COMMERCIAL STYLE INFEED ROLLERS -
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.
DRIVEN GEAR BOX AND DRIVE AXLE SYSTEM
The in-feed 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.
QUICK HITCH COMPATIBLE -
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 requires 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
SWIVEL DISCHARGE CHUTE -
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.
FOOTPRINT SKID TYPE SUPPORT BASE
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 angle upward on the end to prevent digging into the
ground while transporting.
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.
FLOW FLYWHEEL CHAMBER VENTILATION
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
DUTY CAST STEEL BEARING HOUSINGS
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.
SHAFT SUPPORTED BY 3 BEARINGS
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
ADJUSTABLE IN-FEED ROLLER
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-8M... 950lbs (shipping) Steel crate dimentions are L=46" x W=36" x H=48"
More weight = more steel
More strength and stability... period.
THICK FLYWHEEL HOUSING
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.
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.
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.
DUTY 5/8" COGGED DRIVE V-BELTS (STANDARD BX-SERIES)
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
SAFETY AUTO-FEED STOP BAR
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.
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 in-feed ability.
The in-feed hopper on the WM-series wood chippers is horizontal
and approximately table height for easy material loading.
RESISTANT POWDER COAT
The powder coat finish is baked on at 450 degrees, and is thicker
and more durable than ordinary paint.
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.
This robust PTO driven wood chipper comes with an equally robust 3
year warranty. Our service department also stocks a full line of replacement
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.
