bracket (Fig. 39). To level the blade(s), reposition the
leveling bracket(s) in a different hole and install the
washer and hairpin cotter. (Fig. 39). A front hole lowers
the blade height and a rear hole raises its height. Adjust
both sides as required.

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 in.
(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 27.
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 29.
4. Measure the length of the rear trunnion rod (Fig. 40). If
the rod length is not 11-1/2 in. (29.2 cm), remove the
clevis pin and cotter pin from the end of the rod
(Fig. 40), loosen the jam nut, and turn the yoke until the
11-1/2 in. (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.
11-1/2 in.
