2.3 CONNECT PTO DRIVELINE
ASSEMBLY
The driveline supplied with this machine may need to be
cut to a shorter length for proper operation with the tractor
being used. To determine if driveline will need to be cut,
follow steps below or consult attached driveline manual.
1. BEFORE ATTACHING THE DRIVELINE: attach the
machine to the tractor with three-point hitch system.
2. Raise and lower machine on three-point hitch to determine
the shortest possible working distance between the tractor
PTO shaft and the drive shaft of the machine.
3. Pull the driveline apart so the two pieces are separated.
Connect the piece with 6-splined connector to tractor
and the other piece to the machine.
4. Position installed driveline halves parallel to one another.
(Photo below is example of driveline overlap.)
5. On larger outer tube, measure back 1-1/4" (32mm)
from lower yoke shield and mark plastic tube. Repeat
this process for smaller inner plastic tube measuring
1-1/4" (32mm) back from upper yoke shield.
IMPORTANT
• The tractor must have a standard 540 RPM PTO shaft.
• If the tractor has an electric PTO clutch, consult your dealer
for correct operating procedures.
• Consult the attached GKN Walterscheid driveline manual for
complete service and maintenance recommendations.
7. After cutting plastic tubes, measure 1-9/16" (40mm)
from the ends of both newly cut plastic tubes.
8. Mark the inner steel shafts and cut both shafts at 1-9/16"
(40mm) as shown in photos below.

OPERATION
As with any other piece of outdoor equipment, getting the
feel for how your machine operates and getting to know
the best techniques for particular jobs are important to
overall good performance.
CHIPPING OPERATION
The chipping operation takes place on the front of the
machine, where hardened steel chipper blades are
mounted on a rotating disk assembly. Material fed into the
chipper chute is sliced into small chips and propelled out
through a discharge tube.
WARNING
Before operating your machine, be sure you read and
understand all safety, controls and operating instructions
in this owner’s manual and on your machine. Failure to
follow these instructions can result in serious injury or
property damage.
WARNING
Move machine to a clear, level area outdoors before
starting. Do not operate in the vicinity of bystanders.
Make sure cutting chamber is empty before starting.
4.1 STARTING
IMPORTANT
This chipper is designed to be used with a tractor
PTO rated at 25 to 45 horsepower. Using this chipper
with a PTO above 45 horsepower may cause belt and
machine damage in overload conditions
WARNING
Do not inspect or work on PTO drive area without first
disengaging PTO and shutting off tractor.
4.2 STOPPING
1. Move tractor throttle to slowest position.
2. Disengage PTO lever and shut off tractor engine.
3. Allow machine to come to a complete stop.
NOTE
The heavy rotor will continue to turn for some time after
the engine or tractor has been shut off. You can tell
that the rotor has stopped when no noise or machine
vibration is present. Inserting a branch into the chipper
chute to contact the blades will slow the rotor and
shorten stopping time.
1. Connect PTO driveline to tractor as described in Sec.
2.4.3.
2. Adjust three-point top link so the chipper sits level.
3. Start tractor engine and engage PTO (refer to tractor
owner’s manual). Increase engine speed to rated PTO
RPM.

OPERATION
4.3 OPERATING THE CHIPPER
WARNING
Read and follow all safety instructions in this manual.
Failure to operate the machine in accordance with
the safety instructions MAY RESULT IN PERSONAL
INJURY!
CAUTION
Obtain and wear safety glasses at all times when
operating the machine.
Do not wear loose tting clothing.
The operator should always wear heavy boots, gloves,
pants and a long-sleeved shirt.
Use common sense and practice safety to protect
yourself from branches, sharp objects, and other
harmful objects.
The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.
7. If the chipper jams, remove the branch and rotate it
before reinserting it into the chute. Alternately insert
and retract the limb or insert continuously at a rate that
will not kill the engine.
8. Do not use the clutch to clear a plugged rotor. This
may cause belt damage. Refer to the instructions for
clearing a plugged rotor in the Service and Maintenance
section.
9. Alternate greener material with dry material to
lubricate the chipping blades for longer life and better
performance. Chipping dead, dry material will create
heat and dull the chipping blades quickly.
10. Sharpen the chipping blades periodically. Check
the sharpness of the blades every 5-15 hours. Refer
to the Service and Maintenance section for sharpening
instructions.
WARNING
Never lean over the chipper chute to push objects
into the cutting device. Use a push stick or brush
paddle.
1. Run unit at full operating speed before starting to
chip material.
2. Limbs fed in to the chipper chute must be 5" (12,7
cm) in diameter or less. Trim side branches that
cannot be bent enough to feed into the chipper chute.
Hold small diameter branches together in a bundle and
feed in simultaneously.
3. Exclude pieces of metal, rocks, bottles, cans, and
other foreign objects when feeding material into the
machine.
4. Feed brush from the side of the chipper chute, rather
than from the front. Step aside to avoid being hit by the
brush moving into the chipper.
5. Place limb, butt end first, into the chipper chute
until it contacts the chipper blades. The actual feed
rate of the limb into the chipper will depend on the type
of material fed and sharpness of the cutting blades.
6. If the engine slows to where it may stall, stop feeding
material and allow the engine to recover. Feed material
more evenly.
Never use shovels or forks to feed brush. They can
cause extensive damage if they contact the blades.
In addition, metal pieces can be ejected from the
chipper chute and cause serious injury or death.
Never feed brush into the chute with your feet.
Never use hands or feet to clear materials that build up in
the chute.

(2) PERFORM MORE FREQUENTLY WHEN CHIPPING DRY OR DIRTY WOOD.
As the Limited Warranty states, failure by the Owner to perform normal maintenance will void the machine’s warranty.
The aggressive, high-speed nature of chipping REQUIRES THE OWNER TO PERFORM THE ABOVE LISTED NORMAL
MAINTENANCE. Special consideration to maintain and re-torque the CHIPPER ANVIL, CHIPPER BLADES, AND ALL
INTERNAL AND EXTERNAL NUTS AND BOLTS is the sole responsibility of the Owner. Failure by the Owner to do so shall
be cause for denial of warranty.

ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
5.2 CHIPPER BLADE MAINTENANCE
WARNING
The chipping blades are sharp! Use care when
working on machine to avoid injury.
The chipper blades will eventually become dull, making
chipping difcult and adding extra strain on the machine.
CHECK THE SHARPNESS OF THE BLADES EVERY
5 - 15 HOURS OF OPERATION AND SHARPEN AS
NEEDED.
Your blades need to be sharpened if:
• Machine vibrates severely when material is fed into the
chipper.
• Small diameter branches do not self-feed.
• Chips discharge unevenly or have stringy tails,
especially when chipping green branches.
Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:
• There are cracks, broken corners or nicks greater than
1/8" (see below).
5.3 REMOVING THE BLADES
To remove the chipper blades:
1. Remove the retaining bolt that holds the access cover
(see Figure 5.1) to the main frame assembly.
Figure 5.1, Rotor access cover
2. Tilt access cover over to allow rotor access. Rotate
the rotor so that the bolts holding a chipping blade are
most accessible.
3. Remove the two 5/16" bolts holding the chipper blade.
Repeat for all four blades. The four chipping blades
have two edges per blade and can be reversed one
time each before sharpening. If both sides have not
been used, remove and reverse the chipping blades.
4. Reinstall chipping blades and torque to 25 ft-lbs.

5.4 SHARPENING THE BLADES
The blades can be ground on a bench grinder or by a
professional.
1. Never sharpen or grind the mounting surfaces of the
blades. This will cause the edge to roll and the blade will
be damaged, resulting in poor chipping performance.
2. Regrind the angled edge of the chipping blades to 45
degrees (Figure 5.2). Make sure some type of xture is
used to correctly hold the blade at the proper angle.
3. Be careful when grinding so that the blade does not
become overheated and change color. This will remove
the heat-treated properties.

WARNING
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE AND MAKE SURE
ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
4. Use short grinding times and cool with water or some
type of liquid coolant.
5. Remove an equal amount off each blade to maintain
rotor balance.
6. Small imperfections such as nicks and burrs on
the at side of the blade will not affect the chipping
performance of the machine.
7. For blades that have been repeatedly sharpened,
ensure that the sharpened surface extends past the
chipping slot opening. If it does not extend past the
opening, the blades should be replaced.
5.5 SETTING THE BLADE CLEARANCE
The chipping blades should clear the anvil by 1/16" to
1/8". Check the clearance every 8 hours of operation and
adjust if needed. The chipping anvil is reversible. All four
sides of the anvil can be used for chipping.
4. Tighten bolts on chipping anvil to 75 ft-lbs. Make
sure all blades clear the anvil by 1/16" to 1/8" before
operating.
If the chipping anvil edge is damaged or worn unevenly,
remove the two bolts holding the anvil and use one of the
other three edges. Adjust for correct measurement.
5.6 ADJUSTING/REPLACING DRIVE BELT
Check the condition of the drive belt annually or after every
25 hours of operating, whichever comes first. If the belt is
cracked, frayed, or worn, replace it. To replace or adjust
drive belt, proceed as follows:
1. Disengage PTO and shut tractor engine off.
2. Remove belt guard.
3. Remove idler pulley by removing its 1/2 x 4-1/2" bolt,
spacers, washer and nut. Take the drive belt off the
pulleys (Figure 5.4)
4. Install the new belts and reinstall idler pulley.
5. Check pulley alignment with a straight edge and adjust
if needed.
ENGLISH
Figure 5.3, Chipping anvil location
To Adjust the Chipping Anvil:
1. Lift rotor access cover and expose rotor. Loosen
the two 1/2" bolts that hold the chipper anvil to the
frame.
2. Measure the amount of clearance between chipping
blade and chipping anvil from inside of housing.
3. Adjust inward or outward to desired measurement.
6. Check belt tension and adjust if needed. The belt
deflection at the center of the belt should be 7/16" when
a 20 lb. load is placed against it.
7. Reinstall belt guard.
8. Start tractor engine and engage PTO drive clutch (see
tractor owner's manual). Increase engine speed to rated
PTO RPM. Test unit and adjust pulleys if needed.

5.7 REPLACING ROTOR BEARINGS
1. Remove the 3/8" retaining bolt holding access cover to
main frame assembly. Tilt access cover over to allow
rotor access.
2. Remove large belt guard.
3. Remove idler pulley and drive belts. Using the push
bolts from the bushing, remove the bushing, spacer
and pulley from the rotor shaft.
4. Remove the two 1/2" bolts on each rotor bearing and
remove the roll pin from the rotor shaft.

7. Replace roll pin.
8. Use the overhead hoist or lifting device to return the
complete rotor assembly to the chipper frame.
9. Slide rotor back until the roll pin is tight against the front
bearing. Lock the front bearing and install the 1/2" bolts
on each bearing to secure them to the frame. Tighten
bolts to 75 ft-lbs. . Lock rear bearing.
5.8 CLEARING A PLUGGED ROTOR
1. Shut off power source and allow all moving parts to come
to a complete stop.
2. Remove the retaining bolt holding the access cover to
the main frame assembly and lift up access cover.
3. Clean the debris out of the chipping rotor. Turn the rotor
by hand to be sure it is free to rotate.
4. Close rotor access cover and replace bolt.
5. Start engine and engage drive belt to resume
operation.
5.9 LUBRICATION
Lubricate the machine periodically with a lithium-based
grease. Extreme working conditions will require more
frequent greasing.
Grease the following points every 50 hours of operating
time:
• Two bearings on the rotor shaft.
• One grease zerk on the discharge chute.
• One grease zerk behind pulley.
• One grease zerk underneath bearing.
10. Slide spacer and bushing onto shaft with flange against
bearing and lock bushing to shaft. Attach rotor pulley to
bushing. Replace drive belts and reinstall idler pulley. Check
and adjust chipper anvil if needed. Check alignment of
pulleys and belt tension. Adjust if needed.
