Checking the Tire Pressure
Service Interval:
Every 50 hours/Monthly (whichever
comes first)
Maintain the air pressure in the rear tires at 12-14 psi
(83-97 kPa). Uneven tire pressure can cause an uneven
cut.
Note:
The front tires are semi-pneumatic tires and do
not require air pressure maintenance.

Service Interval:

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 55).
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 the bearings (Figure 55).
Important:
Make sure spring washers are
installed correctly as shown in Figure 55.
5. Install the dust cap (Figure 55).

Servicing the Caster Wheel
and Bearings
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 (Figure 56).
