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 20) in the Maintenance
Section.
1. Park the machine on a level surface, disengage
the blade control (PTO), shift into neutral, 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
are not within 3/16" (5 mm), an adjustment is
required; refer to steps 5 and 6.

(Fig. 48). A front hole lowers the blade height
and a rear hole raises its height. Repeat this
procedure on the opposite side.

6. Now check the front-to-rear blade slope; refer to
Front-to-Rear Blade Slope, page 38.

Front-to-Rear Blade Slope

Check the front-to-rear blade slope any time you
install the mower. Before you check the slope, set the
air pressure in the front and rear tires to the
recommended inflation. Refer to "Tire Pressure"
(page 20) in the Maintenance Section. If the front of
the mower is not within a range of 1/8"–3/8"
(3.5mm–10.5mm) lower than the rear of the mower,
adjust the blade slope using the following
instructions:
1. Park the machine on a level surface, disengage
the blade control (PTO), shift into neutral, set
the parking brake, and turn the ignition key to
"OFF" to stop the engine. Remove the key.
2. Check and adjust side-to-side blade level if you
have not checked the setting; refer to
Side-to-Side Mower Leveling, page 38.
