WoodMaxx ™ WM-8H FEATURES INCLUDE:
STRENGTH IN DESIGN
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-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” IN-FEED OPENING
WM-series wood chippers offer a larger 8”x 8” in-feed 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 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 200lbs flywheel is ideal for this size of
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
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.
NEW FOR 2016
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
WM-8H chippers are complete with a self-contained hydraulic pump and a
38l/7 gallon reservoir tank to power the 2 in-feed 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.
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
NYLON PROTECTIVE HYDRAULIC HOSE
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
PRESSURE COMPENSATION FLOW CONTROL
The addition of this valve allows for very precise
in-feed roller speed without causing back pressure on the hydraulic pump.
This allows the user to regulate the speed of the in-feed rollers to
exactly match their tractors capabilities while increasing the life of the
VARIABLE SPEED DUAL HYDRAULIC
speed (10-75ft. /min) aggressive dual counter-rotating hydraulic powered
in-feed rollers work together to pull material into the chipper head. This
feature allows the user to slow the in-feed speed down to accept large
6.25 DIAMETER HARDENED STEEL
COMMERCIAL STYLE IN-FEED ROLLERS
– WoodMaxx ™ EXCLUSIVE
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 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 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 in-feed rollers with high carbon steel chisel teeth.
This type of in-feed roller is found on larger, much more expensive
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 165lbs 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.
QUICK HITCH READY – WoodMaxx ™ EXCLUSIVE
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 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 wood chipper.
Attaching the chipper to your quick hitch takes only seconds. Please note, you'll need the USA 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 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.
WIDE FOOTPRINT SKID TYPE SUPPORT
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 angle upward on the end
to prevent digging into the ground while transporting.
AUTOMATIC BELT TENSIONER – WoodMaxx ™ EXCLUSIVE
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 ™ EXCLUSIVE
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
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
MAIN SHAFT SUPPORTED BY 3 BEARINGS
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
FULLY ADJUSTABLE IN-FEED ROLLER
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
165lbs of down pressure. This allows the teeth on the roller to dig into
the branches and ensure a smooth entry into the chipper head.
weight = more steel
strength and stability…period.
8mm THICK FLYWHEEL HOUSING
WM-series wood 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 ¼” steel.
EASY KNIFE ACCESS PANELS
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 in-feed bin to hold the head of the bolt, while someone else turns the
nut from the backside of the flywheel.
ADJUSTABLE BED [ ANVIL ] KNIFE
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
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
SAFETY AUTO FEED STOP BAR
is paramount on WoodMaxx™ chippers. Located on the top of the in-feed bin,
the WM-8H utilizes an easy to activate hydraulic 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. By simply pulling down on the bar, the user can
stop and even reverses the direction of the in-feed rollers.
HANDY FEED ROLLER ASSIST HANDLE
LOCATED ON TOP OF MACHINE
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.
HORIZONTAL IN-FEED HOPPER
The in-feed hopper on the WM-series wood chippers is
horizontal and approximately table height for easy material loading.
RUST RESISTANT POWDER COAT
powder coat finish is baked on at 450 degrees, and is thicker and more
durable than ordinary paint.
CLEAR VINYL BAFFLE
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
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 imported PTO shaft, but for an additional $150.00 up-charge we do
offer a very high quality Made in the USA shaft. The USA shaft retails for
$250 if purchased separately. NOTE: USA shaft does not work on Kubota BX-series tractors.
