Replacing Push Arm Bushings
The push arms have pressed in bushings on the end
mounted to the traction unit. To check the bushings,
move the push arms side-to-side and examine for
wear. If a push arm is loose, the bushings are worn
and must be replaced.

Remove the mower: refer to Removing the
Mower in the Installation section.
2.
Inspect the pivot pin assembly for wear and
replace if necessary.
3.
Remove the retaining ring and flat washer
securing the push arm to the mower (Fig. 39).
