2.6 CONNECT PTO SHAFT
Attach chipper to tractor with 3 point hitch. Adjust the 1.
machine up and down to find the shortest distance
between the chipper rotor shaft and tractor PTO. Stop
the machine in the shortest position.
Pull the driveline into two pieces. Connect one end to 2.
the tractor PTO and the other end to the chipper rotor
shaft. Line up the two halves parallel to each other.
If the shaft of one half extends past the end shield of
the other half as seen in Figure 2.5, you will need to
shorten the driveline. If your driveline is not too long,
skip to step 7.
Measure the distance from the end of the driveline tube 3.
to the bottom of the end shield of the other driveline half
(Dimension “A” in Figure 2.5). Measure and mark the
driveline tube 1-9/16” inward from Dimension “A.”
Cut the shield tube in the marked position.4.
Using the cut piece of shield tube as your measure-5.
ment, place the cut piece against the end of the shaft.
Mark and cut the shaft.
Repeat step 5 for the other half of the driveline, file both 6.
shaft ends, and slide the two halves back together.
Connect the driveline to the chipper rotor shaft using 7.
key stock and two set screws contained in the owner’s
kit.
Connect the opposite end of the PTO shaft to the 8.
tractor.

CONTROLS AND OPERATION
3.2 OPERATION
3.2.1 STARTING
1. Place tractor transmission in park or neutral and set
parking brake. Connect 3 point mounts between the
chipper and tractor. Secure connections with snap pins.
Adjust 3 point top link so that the chipper sits level.
2. Connect PTO shaft to tractor. Make sure you are using
the correct RPM machine. Do not operate machine at
speeds different than specified on shield.
3. Never inspect or work on PTO drive area without first
disengaging PTO, shutting off tractor engine and waiting for all moving parts to stop.
4. Start tractor engine and engage PTO drive clutch (see
tractor owner's manual). Increase engine speed to
rated PTO RPM position.
WARNING
Do not leave machine unattended or attempt any
inspection unless PTO is disengaged and tractor engine
is shut off. Allow moving parts to come to a complete
stop.
3.2.2 STOPPING
To stop machine, proceed as follows:
1. Move tractor throttle to SLOW 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.
WARNING
Please read and follow all safety instructions in this
manual. Failure to operate the chipper in accordance
with the safety instructions MAY RESULT IN PERSONAL
INJURY!
3.2.3 CHIPPING
This chipper is designed to chip a variety of materials into
a more readily decomposing or handled condition. The
following guidelines can be used to help you get started.
Be sure the unit is at full operating speed before you 1.
start to chip material.
Trim side branches that cannot be bent enough to feed 2.
into the chipper chute. Small diameter branches can be
held together in a bundle and fed in simultaneously.
Feed brush from the side of the chute, rather than 3.
from the front. Then, step aside to avoid being hit by
the brush moving into the chipper.
Never lean over the chute to push objects into the cut-4.
ting device. Use a push stick or brush paddle.
WARNING
Keep face and body away from the feed opening. Do
not over reach. Keep proper balance and footing at all
times.
Never use shovels or forks to push brush. They can 5.
go through the chipper, are expensive to replace, and
cause major damage. In addition, metal pieces can
be shot back like shrapnel to injure or kill the operator
or bystanders.
Never push brush into the feed chute with your feet.6.
Engage the hydraulic feed by moving the control arm. 7.
Pull the arm toward you to engage the hydraulic feed.
In the forward direction, the feed rate increases as the
arm is moved.
Place limb, butt end first, into the chipper chute until it 8.
contacts the hydraulic feed roller and is drawn into the
chipper blades. The actual feed rate of the limb into
the chipper will depend on the type of material fed and
the sharpness of the cutting blades.
If the chipper jams, reverse the feed by moving the 9.
control arm in the reverse direction. 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.
Chipping dead, dry material will create heat and dull the 10.
chipping blades quickly. Alternate greener material with
dry material to lubricate the chipping blades for longer
life and better performance. When the chipping blades
become dull, they will require sharpening. Refer to the
Service and Maintenance section for more information
on sharpening blades.
CAUTION
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 shirt. Use common sense and practice safety to
protect yourself from branches, sharp objects and
other harmful objects.

HYDRAULIC FEED
4.1 HYDRAULIC FEED INSTRUCTIONS
CAUTION
Handle pressurized hydraulic fluid carefully. Escaping
pressurized hydraulic fluid can have sufficient force to
penetrate your skin causing serious injury. This fluid
may also be hot enough to burn. Serious infection or
reactions can develop if proper medical treatment is
not administered immediately.
4.1.1 FLUIDS
Premium hydraulic fluids containing high quality rust,
oxidation and foam inhibitors are required. These include
premium turbine oils, API CD engine oils per SAE J183,
M2C33F or G automatic transmission fluids meeting Allison
C-3 or Caterpillar TO-2, and certain specialty agricultural
tractor fluids.
4.1.2 HYDROSTATIC PUMP START UP PROCEDURE
Follow this start-up procedure when starting a new
installation or when restarting an installation in which the
hydrostatic pump has been removed from the system.
7. A motor fitting may have to be loosened and oil-bled
to remove air from the system (use same procedures
as steps 3-5).
8. Disengage PTO, check for and correct any fluid leaks,
and check the reservoir level. Add fluid if necessary.
The hydrostatic pump is now ready for operation.
Figure 4.1, Hydrostatic pump components
4.2 CONTROL ARM OPERATION
1. Engage the PTO. Bring the chipper up to operating
speed. See Section 3, "Controls and Operation," for
starting, chipping and stopping instructions.
1. Before starting the hydrostatic pump, make sure all system components (reservoir, fittings, etc.) are clean.
WARNING
Do not start engine unless pump is in neutral or detent
position on the cable.
2. Fill the reservoir with recommended hydraulic fluid,
which should be filtered before entering the reservoir.
3. The inlet line leading from the reservoir to the charge
pump must be filled before start-up. Loosen the fitting
on this inlet line until oil bleeds out.
4. Start the engine and run at the lowest possible RPM.
5. As air is purged from the unit, the oil level in the reservoir will drop and bubbles may appear in the fluid.
Refill the reservoir as necessary.
6. Run the unit in both directions for several minutes until
any remaining air is purged from the unit. Refill the
reservoir as necessary.
2. Engage the hydraulic feed by moving the control arm
as shown in Figure 4.2. In the forward direction, the
feed rate increases as the arm is moved.
3. Feed the branch (up to eight or nine inches in diameter,
depending on model number).
4. If the chipper jams, reverse the feed by moving the
control arm in the reverse direction. Remove the branch
and rotate it before inserting it into the chute again.

HYDRAULIC FEED
4.3 HYDRAULIC FEED MAINTENANCE
NOTE: Check the reservoir daily for proper fluid level, the
presence of water (noted by a cloudy to milky appearance,
or free water in bottom of reservoir), and rancid fluid odor
(excessive heat).
The hydrostatic pump normally does not require regular
fluid changes. The system filter should be changed at
either 250 hour or annual intervals, whichever comes
first. The fluid and filter should be changed and system
cleaned if the fluid becomes contaminated with foreign
matter (water, dirt, grease, etc.) or if the fluid has been
subjected to temperature levels greater than the maximum
recommended.
There is a greaseable bearing on each side of the main
jack shaft on the main hydraulic feed housing. Grease
periodically.
4.4 SAFETY BAR (72854S)
4.4.1 RESETTING THE CHIPPER
The safety bar located along the chute extension tray will
stop the chipper when pushed in. The reset button for this
bar sits on top of the chipper chute. When the safety bar
has been activated, a red light will come on signaling that
the operator reset button will need to be pushed before the
feed roller will function. If false trips occur, the reset button
can be held in to override the system. Upon start-up, the
safety bar light will be on and will need to be reset before
the feed roller will operate.
4.4.2 LOCKING IN TRAVEL POSITION
The safety bar will lock into travel position. Place the
extension tray in an upright position. Pushing the safety bar
down will lock the bar. To unlock, lower the extension tray
and push in on the safety bar. This will release the flange
and allow the safety bar to move freely.

SERVICE & MAINTENANCE
Section
WARNING
Before inspecting or servicing any part of the machine,
disengage PTO and make sure all moving parts have
come to a complete stop. The chipping blades are sharp!
Use care when working on machine to avoid injury.
WARNING
CHIPPING BLADE SHARPENING TIPS
Poor chipping performance is usually a result of dull
chipping blades. If your chipper's performance has
decreased, check for the following symptoms:
• Severe vibration when feeding material into the chipper.
• Small diameter branches do not self-feed.
• Chips discharge unevenly or have stringy tails–espe-
cially when chipping green branches.
The rotor assembly has a lock mechanism. When
working on the rotor assembly, use the lock mechanism
at all times. Remove plastic bearing cover under the
chipper chute. There is a hole in the rotor jack shaft
and a matching hole in the bracket mounted to the rotor bearing front side. Install a punch through the rotor
shaft and bracket to lock the rotor in place.
6.1 SHARPENING CHIPPER BLADES
The chipper blades will eventually become dull, making
chipping difficult. It is recommended that the chipper blades
are sharpened every 5-15 hours of chipper operation. To
remove the chipping blades for sharpening:
1. Remove the two 3/8 inch retaining bolts holding access
cover to main frame assembly.
2. Tilt access cover over to expose rotor. Rotate the rotor so that the bolts holding a chipping blade are most
accessible.
3. Remove the two hex nuts holding the blade itself.
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.
Reinstall chipping blades and proceed with chipping.
To grind the angled edge of the chipping blade to 45
degrees (see Figure 6.1): Grind the blades on a slowspeed wet grinder if possible, or have them sharpened
by a professional. If you use a bench grinder, be careful
when grinding so that the blade material does not get too
hot and change color–this will remove the blade's special
heat treated properties. Use short grinding times and cool
with water. Try to remove an equal amount off each blade to
maintain balance. Replace the chipping blades and tighten
bolts to 120 ft-lbs. Close cover and replace bolts.
Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:
• The blade is cracked (especially around the bolt holes)
or the edges are too deeply chipped to be ground
smooth.
• The base of the cutting edge is worn or has been re-
sharpened so that it is too close to the rotor chipping
slot.
Figure 6.1, Sharpening the chipper blades
6.2 SETTING BLADE CLEARANCE
The four-edged chipping anvil located directly behind the
chipper chute should clear the chipping blade by 1/16
inch to 3/16 inch. The chipping anvil is adjustable and
reversible.
To Adjust:
1. Lift rotor access cover and expose rotor. Loosen the
three 1/2 inch 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.
4. Tighten bolts on chipping anvil to 75 ft. lbs. and resume
operation.
PTO CHIPPERS
17
SERVICE & MAINTENANCE
6.2 SETTING BLADE CLEARANCE (CONT.)
If the chipping anvil edge is damaged or worn unevenly,
remove the three bolts holding the anvil and use one of the
other three edges. Adjust for correct measurement.
6.3 ADJUSTING/REPLACING DRIVE BELT
Check the condition of the drive belt annually or after every
30 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:
Disengage PTO and shut off tractor engine.1.
Remove PTO shaft from tractor; disconnect machine 2.
from 3 pt. hitch.
Remove round shield connected to belt guard that 3.
covers PTO shaft by removing two 5/16" nuts.
Remove belt guard covering pulleys and belts.4.
Remove spring loaded idler pulley off of belts and 5.
remove belt.
Install new belt and reverse above instructions to 6.
complete belt replacement.
Two greaseable bearings on the bottom jack shaft.•
One on idler arm pivot.•
One on discharge chute.•
6.6 REPLACING BEARINGS
1. Remove the two 3/8 inch retaining bolts holding access
cover to main frame assembly. Tilt access cover over
to allow rotor access.
2. Remove large belt guard (three 5/16 inch bolts).
3. Loosen bolts on hydraulic pump and remove hydraulic
pump belt. Using the push bolts from the bushing,
remove the bushing and pulley from the rotor shaft.
4. Remove idler pulley and belts. Using the push bolts
from the bushing, remove the bushing and pulley from
the rotor shaft.
5. Remove the four 1/2 inch bolts on each rotor bearing
and remove the punch used to lock the rotor.
6. Using an overhead hoist or lifting device, lift the rotor
assembly completely out of the frame. The complete
rotor assembly is 275 lbs.
6.4 CLEARING PLUGGED ROTOR
WARNING
If the machine becomes plugged, shut off the tractor
engine, and allow the machine to come to a complete
stop before cleaning debris. Do not operate the machine without proper guards and screens in place.
If too large of material or too much material is fed into the
chipper, it may become plugged. To clear a plugged rotor,
proceed as follows:
1. Disengage PTO and shut off tractor engine.
2. Lift rotor 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. Replace rotor access cover.
5. Start tractor, engage PTO, and resume operation.
6.5 GREASEABLE BEARINGS
The PTO model has ten grease zerks on it. Minimal periodic
greasing is needed on these points every 50 hours:
Four grease zerks on the PTO shaft itself.•
Two greaseable bearings on the rotor shaft. •
7. Once the rotor assembly is out of the frame, remove
3/8" bolt and collar from front. Remove both bearings
and place new bearings on rotor shaft. Replace collar.
8. Use the overhead hoist or lifting device to return the
complete rotor assembly to the chipper frame.
9. Slide rotor back until front collar is tight against the
front bearing. Lock the front bearing and install the
four 1/2 inch bolts on each bearing to secure them to
the frame. Tighten bolts to 75 ft-lbs. Check and adjust
chipper anvil if needed. Lock rear bearing.
10. Slide rear collar on shaft against rear bearing. Slide
bushing onto shaft with flange against collar and
lock bushing to shaft. Attach large pulley to bushing.
Replace drive belts on pulleys and install idler pulley.
Check alignment of pulleys with straight edge and
adjust if needed.
11. Close cover and replace bolts.
12. Replace hydraulic pump bushing and pulley. Replace
hydraulic pump belt. Readjust hydraulic pump belt
tension by sliding the hydraulic pump in the mounting
slots. Tighten bolts.
13. Replace belt guard and resume operation.
14. Start tractor engine and engage PTO drive clutch (see
