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. 33).
2.
Remove one bushing, then pull the spanner
bushing and roller bearing out of the wheel hub
(Fig. 33).
3.
Remove the other bushing from the wheel hub
and clean any grease and dirt from the wheel hub
(Fig. 33).
4.
Inspect the roller bearing, bushings, spanner
bushing and inside of the wheel hub for wear.
Replace any defective or worn parts (Fig. 33).

To assemble, place one (1) bushing into the
wheel hub. Grease the roller bearing and spanner
bushing and slide them into the wheel hub. Place
the second bushing into the wheel hub (Fig. 33).
6.
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 forks (Fig. 33).
7.
Grease the fitting on the castor wheel.
Storage
1.
Clean any dirt and chaff from the top of the
mower.
2.
Scrape any heavy buildup of grass and dirt from
the underside of the mower, then wash the
mower with a garden hose.
3.
Check the condition of the blades. Refer to
Cutting Blades on page 11.
4.
Check the condition of the drive and deck belts.
5.
Check and tighten all bolts, nuts and screws.
Repair or replace any part that is damaged or
defective.
6.
Paint all scratched or bare metal surfaces. Paint
is available from your Authorized Service

Store the machine in a clean, dry garage or
storage area. Cover the machine to protect it and
keep it clean.
