Replacing Drive Belts

The blade drive belts, tensioned by the spring loaded idlers,
are very durable. However, after many hours of use, the
belts will show signs of wear. Signs of a worn belt are:
squealing when belt is rotating, blades slipping when
cutting grass, frayed edges, burn marks, and cracks.
Replace the belt if any of these conditions are evident.

1. Lower cutting unit to the shop floor. Remove belt

covers from top of cutting unit and set covers aside.

2. To replace gear box belt, loosen spring tension rod and

remove belt. Retention new belt to 30 lb. Refer to
Figure 33 for belt routing.

3. To replace wing belts, loosen spring tension rod and

remove gear box belt.

4. Pull spring loaded idler pulley away from belt, with

hand, to relieve belt tension and remove belt. Retention
new belts to 10 lb. Refer to Figure 33 for belt routing.

5. Install belt covers.

Servicing Front Bushings In
Castor Arms

The castor arms have bushings pressed into the top and
bottom of the tube and after many hours of operation, the
bushings will wear. To check the bushings, move castor
fork back and forth and from side to side. If castor spindle
is loose inside the bushings, bushings are worn and must be
replaced.

1. Raise cutting unit so wheels are off floor and block it so

it cannot fall accidentally.

2. Remove tensioning cap, spacer(s) and thrust washer

from top of castor spindle.

3. Pull castor spindle out of mounting tube. Allow thrust

washer and spacer(s) to remain on bottom of spindle.

4. Insert pin punch into top or bottom of mounting tube

and drive bushing out of tube. Also drive other bushing
out of tube. Clean inside of tubes to remove dirt.

tube. Slide thrust washer and spacer(s) onto spindle.
Install tensioning cap on castor spindle to retain all parts
in place.
