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 (Figure 35).
Note: The front tires are semi-pneumatic tires and do
not require air pressure maintenance.
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
pivot 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. Raise the cutting unit so the caster wheels are off
the floor, then support the front of the mower with
jack stands.
2. Remove the locking pin and spacer(s) from the top
of the caster wheel fork (Figure 36).

3. Pull the caster wheel fork out of the mounting tube,
leaving the spacer(s) on the bottom of the fork.
Remember the location of the spacers on each fork
to ensure correct installation, and to maintain a level
deck.
4. Insert a pin punch into the mounting tube and
carefully drive out the bushings (Figure 37). Clean
the inside of the mounting tube.
