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

floor, then block up the front of the mower with jack
stands.
2. Remove the locking pin and spacer(s) from the top of
the caster wheel fork (Fig. 62).
