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.
1. Position the mower on a flat surface. Disengage the
PTO, set the parking brake, stop the engine, and
remove the key. Disconnect the spark plug wire(s)
from the spark plug(s).
2. Check the air pressure of all four tires. If needed,
adjust to the recommended inflation; refer to Tire
Pressure, page 29.
3. Set the height-of-cut at 3 inch (76 mm).
4. Carefully rotate the blade(s) from side to side
(Fig. 37). Measure between the outside cutting edges
and the flat surface (Fig. 37). If both measurements are
not within 3/16 inch (4.75 mm), an adjustment is
required; refer to steps 5 and 6.

5. Remove the hairpin cotter and washer from the
leveling bracket (Fig. 38). To level the blade(s),
reposition the leveling bracket(s) in a different hole
and install the washer and hairpin cotter. (Fig. 38). A
front hole lowers the blade height and a rear hole
raises its height. Adjust both sides as required.

6. Check the front-to-rear blade slope; refer to Adjusting
the Front-to-Rear Blade Slope, page 30.
Adjusting the Front-to-Rear
Blade Slope
Check the front-to-rear blade level any time you install
the mower. If the front of the mower is more than
5/16 inch (7.9 mm) lower than the rear of the mower,
adjust the blade level using the following instructions:
1. Position the mower on a flat surface. Disengage the
PTO, set the parking brake, stop the engine, and
remove the key. Disconnect the spark plug wire(s)
from the spark plug(s).
2. Check the air pressure of all four tires. If needed,
adjust to the recommended inflation; refer to Tire
Pressure, page 29.
3. Check and adjust the side-to-side blade level if you
have not checked the setting; refer to Leveling the
Mower from Side-to-Side, page 30.
4. Measure the length of the rear trunion rod (Fig. 39). If
the rod length is not 11-1/2 inch (29.2 cm), remove the
clevis pin and cotter pin from the end of the rod
(Fig. 39), loosen the jam nut, and turn the yoke until
the 11-1/2 inch (29.3 cm) dimension is obtained. Then
secure the yoke with the clevis pin and cotter pin.
Repeat this procedure on the opposite side of the
mower.
