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 "Tire Pressure" (page 21) in the Maintenance
Section.

the blade control (PTO), set the parking brake,
and turn the ignition key to "OFF" to stop the
engine.
2. Remove the key from the ignition switch and
pull the wire off the spark plug.
3. Move the height-of-cut lever (deck lift) into the
"C" notch.
4. Carefully rotate blade(s) side to side (Fig. 47).
Measure between the outside cutting edges and
the flat surface (Fig. 47). If both measurements
