ASSEMBLY
2.4 PTO DRIVELINE CONNECTION
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.)
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.
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.

9. File both shaft ends to remove sharp edges and slide
the driveline pieces back together.
10. When you have confirmed that the driveline is the
correct length for your tractor, connect the driveline
to the chipper rotor shaft using key stock and two set
screws in the owner’s kit.
11. Connect the opposite end of the PTO shaft to the
tractor.
6. Remove driveline pieces (for ease of cutting) and cut
ONLY the outer and inner plastic tubes.

FEATURES & CONTROLS
1. Three point hitch connection: Mounts chipper to
tractor three point hitch.
2. PTO shaft: Connects chipper to tractor PTO shaft.
Avoid driveline angles over 20 degrees on PTO shaft
when unit is in use. NOTE: Minimum and maximum
telescoping on the PTO shaft is 18.11" to 24.49".
This will leave a 6.43" overlap. See Section 2.8 for
instructions on checking shaft length.
3. Front belt shield: Covers the chipper drive pulley.
4. Rear belt shield: Covers the PTO driven pulley.
5. Belt engagement lever: During engine start-up,
the engagement handle must be in the disengaged
position. Engage the rotor by slowly moving the
engagement handle to the engaged position, allowing
the rotor to speed up gradually, and then increase the
throttle to full throttle position. Engaging the clutch too
7

quickly with the engine at full or half throttle will bog
down the engine and will shorten the life of the belt.
To disengage the rotor, first idle the engine down and
then move the engagement handle to the disengaged
position.
6. Chipper chute: Feed materials to be chipped through
the chipper chute.
7. Rotor access cover: Remove to expose chipper
blades.
8. Discharge cap: Chipped materials exit through
the discharge cap. A discharge tube is an available
alternative.

OPERATION
CAUTION
Move the machine to a clear, level area outdoors before
starting. Do not operate in the vicinity of bystanders. Make
sure the cutting chamber is empty before starting.
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.
4.1 STARTING PTO CHIPPER
1. Connect PTO driveline to tractor as described in Sec.
2.4.
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.
4.2 STOPPING PTO CHIPPER
1. If the tractor is able to stop the chipper with the chipper
engagement lever in the CHIPPING position, it is not
required to place the chipper engagement lever in the
START position when stopping the tractor PTO. If the
tractor PTO cannot stop the chipper with the chipper
engagement lever in the CHIPPING position, move the
chipper engagement lever to the START position.
2. Move the tractor throttle to the SLOW position.
3. Disengage the PTO lever and shut off the tractor
engine.
4. Allow machine to come to a complete stop.
4.3 OPERATING THE CHIPPER
CAUTION
Obtain and wear safety glasses at all times when
operating the machine.
Do not wear loose fitting 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.
WARNING
Never lean over the chipper chute to push objects into the
cutting device. Use a push stick or brush paddle.
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.
The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.
1. Run unit at full operating speed before starting to
chip material.
2. Limbs fed in to the chipper chute must be 4.5 inches
11 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.
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.

mechanism at all times (Figure 5.1). Follow the steps below
to install the disk lock:
1. Remove the chipper deflector.
2. Rotate the chipper disk until the hole on the chipper
paddle is aligned with the hole on the chipper housing
(Figure 5.1).
3. Install a punch or screwdriver into the holes.
NOTE
One of the 3/8" x 5-1/2" bolts from the chipper deflector
can also be used to lock the disk.

5.3 CHIPPER BLADE MAINTENANCE
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:
5.4 REMOVING THE BLADES
WARNING
Chipping blades are sharp! Use caution when working
on machine to avoid injury.
1. Remove the chipper deflector from the chipper housing
by removing the two 3/8" x 5-1/2 bolts securing the
discharge cap or optional discharge tube to the chipper
housing and loosening the 5/6" flange nuts on the
weldment bolts. Remove the discharge cap or optional
discharge tube.
2. Install the disk lock (Section 5.2). The disk is now
restrained for removing the blades. To access the
remaining blade, remove the punch or screwdriver,
reposition the disk and return the punch or screwdriver
to the disk lock hole.
3. Remove the two bolts that hold the blade to the disk.
The hardware can be reused. Repeat for remaining
blade. The blades have two edges and can be reversed
one time before sharpening.
4. Inspect blades to see if cracks or nicks are visible. If
cracks are present, replace the blades. Replace the
blade if nicks cannot be removed by sharpening.

5.5 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. Make sure some type of fixture 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.
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 flat 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.

chipper chute can provide better access for measuring the
chipping blade clearance. To adjust the blade clearance,
proceed as follows:
1. Rotate the disk until a chipping blade is even with the
chipping anvil.
2. Measure the amount of clearance between the chipping
blade and chipper anvil from inside of the chipper
housing. The minimum distance between the chipping
blade and the chipping anvil should be 1/16" (Figure
5.2).
3. Adjust the anvil by loosening the 5/16" x 5/8" bolts
holding the anvil to the disk cover and sliding the anvil
inward or outward until the desired measurement is
achieved.
4. Torque the bolts to 17 Ft-lbs.
5. Rotate the rotor to ensure the remaining blade clears
the anvil by 1/16" to 1/8".
6. If the chipper chute was removed, reinstall it.
WARNING
It is important to ensure that the minimum gap between
the chipping anvil and ALL chipping blades is 1/16". All
chipping blades should be rotated until even with the
chipping anvil and then measured. Failure to do so can
result in the chipping blades striking the chipping anvil,
causing serious injury or death.
