Caster Wheel And Bearings Service; Replacing The Grass Deflector - Toro ProLine 30437 Operator's Manual

Caster Wheel and Bearings
Service
The caster 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 caster wheel usually
indicates a worn bearing.
1. Remove the locknut and wheel bolt holding the caster
wheel to the caster fork (Fig. 69).
2. Remove one bushing, then pull the spanner bushing and
roller bearing out of the wheel hub (Fig. 69).
3. Remove the other bushing from the wheel hub and
clean any grease and dirt from the wheel hub (Fig. 69).
4. Inspect the roller bearing, bushings, spanner bushing
and inside of the wheel hub for wear. Replace any
defective or worn parts (Fig. 69).

Grease the roller bearing and spanner bushing and slide

with the wheel bolt and locknut. Tighten the locknut
until the spanner bushing bottoms against the inside of
the caster forks (Fig. 69).

Replacing the Grass Deflector

Warning
An uncovered discharge opening could allow the
lawn mower to throw objects in the operator's or
bystander's direction and result in serious injury.
Also, contact with the blade could occur.
Never operate the lawn mower unless you install a
cover plate, a mulch plate, or a grass chute and
catcher.
1. Remove the locknut, bolt, spring and spacer holding the
deflector to the pivot brackets (Fig. 70). Remove
damaged or worn grass deflector.
2. Place spacer and spring onto grass deflector. Place the L
end of spring behind deck edge.
Note: Make sure the L end of spring is installed behind
deck edge before installing the bolt as shown in figure 70.
3. Install bolt and nut. Place the J hook end of spring
around grass deflector (Fig. 70).
Important
The grass deflector must be able to rotate.
Lift the deflector up to the full open position and ensure
that it rotates into the full down position.
