14. For GHS (Grass Handling System) equipped

Walker tractors, install a blower intake cover in
the blower intake tube.  The cover “unloads” the
blower and seals the intake to effectively elimi-
nate power loss and noise when the blower is
not being used.  Refer to GHS Blower Intake
Cover illustration for ROTARY BROOM in this
section.

15. For stability of the tractor when transporting with

the snowblower in raised position, approximate-
ly 80 lb (36 kg) of counterweight should be in-
stalled on the tail of the tractor.  Optional tail
weights for the various tractor models are avail-
able from your Walker dealer or a sandbag or
similar weight may be used.

DEBRIS BLOWER

Debris Blower Installation

The debris blower is shipped completely assembled
except for the driveline, which must be connected to
the input shaft.

1.

Remove the belt guard from the debris blower
housing by removing the two (2) cover pins and
hairpins securing it to the housing.

2.

Thoroughly clean the debris blower input shaft
and install a 1/4 x 1/4 x 1-1/4 in. key in the input
shaft keyway.

3.

Thoroughly clean the inside of the tractor PTO
shaft and align the PTO shaft keyway with the
key in the input shaft keyway.

4.

Secure the PTO shaft to the input shaft with a
1/4 x 2-1/2 in. bolt and nylon locknut.  Tighten
the locknut and the set screw over the key.

Attach Tractor PTO to Debris Blower Input Shaft

5.

Reinstall the belt guard by reversing the remov-
al procedure.

6.

Insert the male quick hitch section of the imple-
ment hitch into the female hitch of the debris
blower and lock in place by moving the hitch
locking lever fully forward to the LOCKED po-
sition.  Secure the latch with the linchpin.  Refer
to  Hitch Locking Lever in 

Operating Instruc-

tions.

Attach Debris Blower to Implement Hitch

7.

To install the optional tire chains:

a.

Remove the tractor wheels.

b.

Attach the tire chains to the wheels.

c.

Place the wheel spacer plates on the lug
bolts.  The wheel spacer plates provide
clearance for the chains between the tires
and the tractor body.

d.

Place the wheels back on the tractor.

e.

Reinstall and tighten the lug bolts.

8.

For GHS (Grass Handling System) equipped
Walker tractors, install a blower intake cover in
the blower intake tube.  The cover “unloads” the
blower and seals the intake to effectively elimi-
nate power loss and noise when the blower is
not being used.  Refer to GHS Blower Intake
