3 FEATURES & CONTROLS
Understanding how your machine works will help you achieve the best results when using your chipper. The following
descriptions dene the features and controls of your machine.
1. CHUTE EXTENSION TRAY
CE compliant models. An additional safety feature
to keep the operator from touching or being pulled
into the chipper blades. The extension should be
unlatched and rotated open on its hinge when
transporting the chipper.
2. DISCHARGE CAP
Chipped materials exit through the discharge cap. A
discharge tube is an available alternative.
3. ROTOR ACCESS COVER
Remove to expose chipper blades.
4. CHIPPER CHUTE
Materials to be chipped are fed into the feed chute,
through the feed roller, to the chipper blades.
5. BELT ENGAGEMENT LEVER
During engine start-up, the engagement handle must
be in the disengaged (UP) position. With the engine
at 1/4 throttle, carefully engage the rotor by slowly
pushing the engagement handle down, allowing the
rotor to speed up gradually. Engaging the chipper too
quickly with the engine at full or half throttle will bog
down the engine and will shorten the life of the belt.
See Sections 4.2 and 4.4.
6. PTO DRIVESHAFT
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 2.4 for instructions on
checking shaft length.
7. FRONT BELT SHIELD
Covers the chipper drive pulley.
8. REAR BELT SHIELD
Covers the PTO driven pulley.
9. CAT. I THREE-POINT CONNECTION
Mounts chipper to tractor three-point hitch.
10. BLADE HARDWARE ACCESS PANEL
Allows access to chipper blade hardware.

4 OPERATION
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.
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
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 in the middle of
the machine, where hardened steel chipper blades are
mounted on a rotating rotor assembly. Material fed into
the chipper chute is sliced into small chips and propelled
out through a discharge tube.
4.1 STARTING THE CHIPPER
1. Connect PTO driveline to tractor as described in
Section 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.
If forward and reverse feed positions are reversed
when you power up the machine, you may have
plugged the connectors into the wrong plug.
NOTE
Do not inspect or work on PTO drive area without rst
disengaging PTO and shutting o󰀨 tractor. Allow all
moving parts to come to a complete stop.
WARNING
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 o󰀨 the tractor
engine.
4. Allow machine to come to a complete stop.
The rotor will continue to turn for some time after the
engine has been shut o󰀨. Make sure rotor has stopped
completely before inspecting or servicing machine.
NOTE
4.2 STOPPING THE CHIPPER

10 4.5 INCH CHIPPER
OPERATION
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!
WARNING
4.3 CHIPPER OPERATION GUIDELINES
The machine chips a variety of materials into a more
readily decomposed or handled condition. The following
guidelines will help you get started.
1. Gradually increase engine speed to rated PTO
RPM.
2. ALWAYS run engine at rated PTO RPM before
starting to chip material.
3. If the chipper rotor slows, stop feeding material
and allow the engine to recover. Feed material more
evenly.
4. If the chipper jams, remove the branch, rotate it
before reinserting into the chute. Alternately insert
and retract the limb or insert continuously at a rate
that will not kill the engine.
5. 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.
6. Limbs fed in to the chipper chute must be 4.5"
(11.4 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.
7. Alternate green or fresh cut 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 quicker.
8. ALWAYS 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.
9. ALWAYS place limb, butt end rst, 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.
10. NEVER attempt to clear a plugged rotor or discharge
with the engine running. ALWAYS shut engine
OFF and remove the PTO shaft from tractor before
servicing any part of this machine.
11. NEVER attempt to chip pieces of metal, rock, bottles,
cans or other foreign objects.

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.

The chipper blades will eventually become dull, making
chipping di󰀩cult 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.
●Chips discharge unevenly or have stringy tails,
especially when chipping green branches.
5.3 CHIPPER BLADES MAINTENANCE
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).
●The base of the cutting edge is worn or has been
re-sharpened so that it no longer extends past the
chipping slot (see below).
1. Remove the chipper deector from the chipper
housing by removing the two 3/8 × 5-1/2" bolts
securing the discharge cap or optional discharge tube
to the chipper housing. Remove the discharge cap or
optional discharge tube.
2. Install the rotor lock (Section 5.2). The rotor is now
restrained for removing the blades. To access the
remaining blade, remove the punch or screwdriver,
reposition the rotor and return the punch or screwdriver
to the rotor lock hole.
Chipping blades are sharp! Use caution when working
on machine to avoid injury.

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.
3. Using blade hardware access hole (see Figure 5.2),
remove the two bolts that hold the blade to the rotor.
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.
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 chopping blades to
45 degrees (Figure 5.3). Use the blade angle gauge
plate when sharpening the blades to achieve the
proper angle (see Figure 5.4).
1. Lock rotor assembly (Section 5.2).
2. Place a blade on the rotor and attach using original
hardware. Torque the bolts to 120 ft-lbs (162 Nm).
Repeat for the remaining blade. Install blade hardware
access plate.
3. Reinstall the chipper discharge cap or optional
discharge tube (Section 2.2).
Figure 5.3, Chipper Blade Surfaces
The chipping blades should clear the chipping anvil,
located directly under the chipper chute, by 1/16" to 1/8".
Removing the chipper chute is NOT required for setting
the chipping blade clearance. However, removing the
chipper chute can provide better access for measuring
the chipping blade clearance.
To adjust the blade clearance, proceed as follows:
1. Rotate the rotor until a chipping blade is even with the
chipping anvil.

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 o󰀨 each blade to maintain
rotor balance.
6. Small imperfections such as nicks and burrs on
the at side of the blade will not a󰀨ect 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 (see
Section 5.3).

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 5.6).
3. Adjust the anvil by loosening the 5/16 × 5/8" bolts
holding the anvil to the rotor 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" (not to exceed 1/8").
6. If the chipper chute was removed, reinstall it.
