and left. Identify right and left from the operator's
position (Fig. 112). On the right side, the R should
face outward. The letter L should face outward on
the left side. If the wheel pinions are reversed, the
wheels will not drive.

in the wheel cover. The best way is to assemble the
wheel, wheel cover, and wheel bolt, then put them all
on the mower together.

guide screws. Over-tightening can cause the belt
guide to deform and cause the belt not to declutch
properly. Tighten fi rmly with a ratchet.
