Maintenance
Checking the Tire Pressure
Maintain the air pressure in the front and rear
tires as specified. Check the pressure at the valve
stem after every 50 operating hours or monthly,
whichever occurs first (Figure 38). Check the
tires when they are cold to get the most accurate
pressure reading.
Rear and caster tire pressure: 15 psi (103 kPa)

Replacing the Caster Wheel
Fork Bushings
The caster wheel forks are mounted in bushings
pressed into the top and bottom of the carrier
frame mounting tubes. To check the bushings,
move the caster forks back and forth and
side-to-side. If a caster fork is loose, the bushings
are worn and must be replaced.
1. Disengage the blade control (PTO), set the
parking brake, stop the engine, remove the key,
and disconnect the spark plug wire from the
spark plug.
2. Raise the cutting unit so the castor wheels are
off the floor, then block up the front of the
mower with jack stands.
3. Remove the retaining ring and thrust washer(s)
from the top of the castor wheel fork
(Figure 39).
4. Pull the castor wheel fork out of the mounting
tube, leaving the spacer and thrust washer(s)
on the bottom of the fork.
Remember the location of the thrust washers
and spacer on each fork to ensure correct
installation and to maintain a level mower.
