Leveling the Mower from
Side-to-Side
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 26.
1. Park the machine on a level surface, disengage the PTO,
shift into neutral, set the parking brake, stop the engine,
and remove the ignition key.
2. Pull the wire off of the spark plug.
3. Carefully rotate the blade(s) side to side (Fig. 47).
Measure between the outside cutting edges and the flat
surface (Fig. 47). If both measurements are not within
3/16 in. (5 mm), an adjustment is required; refer to
steps 4 and 5.
