Replacing the Castor Wheel
Fork Bushings
The castor wheel forks are mounted in bushings pressed
into the top and bottom of the carrier frame mounting
tubes. To check the bushings, move the castor forks back
and forth and side-to-side. If a castor fork is loose, the
bushings are worn and must be replaced.
1. Raise the cutting unit so the castor wheels are off the
floor, then block up the front of the mower with jack
stands.
2. Remove the locking pin and thrust washer(s) from the
top of the castor wheel fork (Fig. 29).

3. Pull the castor wheel fork out of the mounting tube,
leaving the thrust washer(s) and the spacer on the
bottom of the fork.
Note: Remember the location of the thrust washers and
the spacer on each fork to ensure correct installation and
to maintain a level deck.
