Servicing the Castor Wheels
and Bearings
The castor wheels rotate on a roller bearing supported by a
spanner bushing. If the bearing is kept well lubricated,
wear will be minimal. Failure to keep the bearing well
lubricated will cause rapid wear. A wobbly castor wheel
usually indicates a worn bearing.
1. Remove the locknut and wheel bolt holding the castor
wheel to the castor fork (Fig. 35).
2. Remove the washer and bushing, then pull the spanner
bushing and roller bearing out of the wheel hub
(Fig. 35).
3. Remove the other washer and bushing from the wheel
hub and clean any grease and dirt from the wheel hub
(Fig. 35).
4. Inspect the roller bearing, bushings, spanner bushing
and inside of the wheel hub for wear. Replace any
defective or worn parts (Fig. 35).

5. Install the washers on the outsides of the bushings,
then install the castor wheel into the castor fork and
secure with the wheel bolt and locknut. Tighten the
locknut until the spanner bushing bottoms against the
inside of the castor fork (Fig. 35).
6. Grease the fitting on the castor wheel.

Replacing the Grass Deflector

1. Remove the locknuts, bolts and springs holding the
deflector mounts to the pivot brackets (Fig. 36).
2. If the pivot brackets need to be replaced, remove the
carriage bolts and cone locknuts holding the old
brackets to the top of the discharge opening, then
install the replacement pivot brackets. Make sure the
carriage bolt heads are on the inside of the cutting unit
(Fig. 36).
3. Install the deflector mounts between the pivot brackets
with the bolts, springs and locknuts. Make sure the
straight ends of the springs are positioned between the
deflector mounts and the grass deflector (Fig. 36).
4. Tighten the locknuts until they contact the pivot
brackets (Fig. 36).
