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.

NOTE

Before mounting the blower to the towable chipper/
shredder, we recommend moving the axle to the rear
position on the trailer base as follows:

1. Raise the trailer so that the wheels clear the
ground.

2. Place blocks under the unit to suppport it.

3. Remove the bolts holding the axle to the trailer.

4. Position the axle so that the bolt holes align with
the two rear holes on the trailer base.

5. Attach the axle with the bolts and torque to the
proper setting.

BEFORE INSTALLING

1. Remove the discharge door and rod. A new rod is
provided with the kit.

2. Remove the rotor shaft end cap as shown below. The
hardware will be used later.

INSTALL BELT GUARD SUPPORT PLATE

Two support plates are provided with the kit. One support
plate is for towable models, the other is for PTO models.
Select the appropriate plate for your machine.

TOWABLE MODELS

The mounting plate measures 16-1/4 x 7-1/2 inches. It
has key stock welded to one end.

NOTE: If your model does not have predrilled mounting
holes, align the mounting plate on the bottom of the
chipper/shredder, mark the positions of the holes on the
bottom of the chipper/shredder frame, and drill two 3/8"
holes through the metal on the frame.

To mount the plate:

1. Apply the seal to the plate as shown below.

2. Align the mounting plate with the 3/8" holes on the
bottom of the chipper/shredder.

3. Attach the mounting plate to the frame using 3/8" x 1"
bolts, washers, and nuts as shown below.

PTO MODELS

The mounting plate has angled supports that bolt on to
the chipper/shredder support leg.

To mount the plate:

1. Support the discharge end of the chipper/shredder
by inserting blocks under the frame until the blocks
support the weight of the chipper/shredder.

2. Remove the four bolts that attach the leg stand to the
chipper/shredder.

3. Slide the mounting plate onto the leg stand.

4. Reattach the leg stand to the front of the chipper/
shredder with four (4) 3/8" x 2-1/2" bolts and nuts as
shown below.

ATTACH BLOWER TO CHIPPER/
SHREDDER

1. Attach foam seals to the top of the chipper/shredder
opening and side lips of the blower as shown.

2. Hold the blower up to the chipper/shredder frame,
install the new rod, and secure with a 5/16" lock
nut on each end. The blower should rest firmly on
the chipper/shredder frame and mounting plate
previously installed.

3. Do not remove debris screen when
installing blower.

4. It may be necessary to loosen the
blower shroud and slide it in for the
proper clearance.

INSTALL IDLER ASSEMBLY

1. Remove rotor shaft cap. Do not discard nuts.

2. Do not remove the two remaining nuts that secure the bearing.

3. Remove the exsisting straight zerk in the rotor bearing and Install the angled (45 degree) grease zerk, provided in
the kit, into the bearing.

4. Place the idler assembly over the rotor shaft bolts. Secure the assembly with the bottom 1/2" nut that was removed
when the rotor shaft end cap was removed. The top nut will be screwed on later.

5. Align the opposite end of the assembly with the mounting holes on the blower mounting plate. Secure with two (2)
5/16" x 1" carrage bolts and nuts.

6. Attach the split bushing to the 6.6" pulley. Follow the Reverse Mount instructions provided with the bushing and
torque to 9 ft-lbs (108 in/lbs). Slide the pulley onto the rotor shaft. Install keys.

7. Mount the inside belt on the 6.6" pulley and connect this belt to the inside (3.6") blower shaft pulley.

8. Align the 6.6" pulley with the inside (3.6") blower pulley using a straightedge. Make any necessary adjustments by
sliding the 6.6" pulley on the rotor shaft. Tighten the 6.6" pulley bushing securely.

9. Attach the split bushing to the 5.2" pulley. Follow the Reverse Mount instructions provided with the bushing and
torque to 9 ft-lbs (108 in/lbs).

OPERATION

See the chipper/shredder owner's manual for starting procedures and additional safety instructions before using the
two-speed blower.

The two-speed blower is designed to be used primarily with the chipper. When using the shredder, limit the size of the
material to 3/4" in diameter and 24" long sticks or twigs to avoid plugging the machine. Smaller diameter discharge
screens can also be used to help prevent plugging. Any material larger than this should be put through the chipper.

NOTE: Always start the chipper/shredder with the two-speed blower control lever in SLOW speed.

CHIPPING

• Adjust the discharge tube and spout before operating.

• Select limbs that are up to 5 inches in diameter. Trim side branches that will not fit into the chipper chute.

• Place limb, butt end first, into the chipper chute until it contacts the chipper blades.

• The actual feed rate of the limb will depend on the type of material fed and sharpness of the chipping blades.

• Insert the limb at a rate that will not kill the engine or stall the tractor.

• Rotating the branch as it is fed in will improve the cutting action.

• The chipper blades will become dull with use and will require periodic sharpening. Refer to the owner's manual for

instructions.

SHREDDING

Place material to be shredded (grass, leaves, garden refuse, twigs, etc.) into the hopper. If necessary, use a leaf tamper,
branch, or similar object to push the material through the inlet brushes. If material is damp, insert small sticks or twigs
into the shredder to help prevent buildup.

FAST SPEED

Use the fast speed to operate the optional 20-foot vacuum (Kit part number 71125). See assembly instructions included
with the vacuum kit.

LUBRICATION

Lubricate the blower periodically with a lithium-based grease. Extreme working conditions will require more frequent
greasing.

Grease the following points every 50 hours of operating time:

• Grease zerk located on the idler arm,

• Grease zerk on discharge tube base.

Lubricate the rest of the chipper/shredder as indicated in your owner's manual.
