from the pulley. Tighten the mounting bolts (Fig. 43).

Side-to-Side Mower Leveling

The mower blades must be level from side to side. Check
the side-to-side level any time you install the mower or
when you see an uneven cut on your lawn. Before you level
the mower, set the air pressure in the front and rear tires to
the recommended inflation; refer to Checking the Tire
Pressure, page 25.

the blade height and a rear hole raises its height. Repeat
this procedure on the opposite side of the mower.
