Checking the Wheel Lug Nuts

Service Interval: After the first 8 hours—Check the torque
on the wheel lug nuts.
Yearly—Check the torque on the wheel lug nuts.
Check and torque the wheel lug nuts to 122 to 136 N-m (90
to 100 ft-lb).
Adjusting the Caster Pivot
Bearing
Service Interval: Every 500 hours/Yearly (whichever comes
first)
1. Disengage the blade-control switch (PTO), move the
motion-control levers to the neutral-locked position
and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Remove the dust cap from caster and tighten lock nut
(Figure 57).
4. Tighten the locknut until the spring washers are flat and
then back off a 1/4 turn to properly set the pre-load on

Adjusting the Electric Clutch

Service Interval: Every 500 hours—Check the electric
clutch.
The clutch is adjustable to ensure proper engagement and
proper braking.
1. Insert a 0.381–0.533 mm (0.015–0.021 inch) feeler
gauge through one inspection slot in the side of the
assembly. Make sure it is between the armature and
the rotor friction surfaces.
Make sure the gap is at least 0.381 mm (.015 inches)
and not more than 0.533 mm (.021 inches).
2. If adjustment is needed, then set at 0.381 mm (.015
inches) for each of the three adjustment slot positions.
Tighten the lock nuts until there is slight binding on
the feeler gauge but it can be moved easily within the
air gap (Figure
3. Repeat this for the remaining slots.
4. Check each slot again and make slight adjustments until
the feeler gauge between the rotor and armature with
very slight contact between them.
