4. Set the height-of-cut lever to position D
[3 inch (76 mm)].
5. Carefully rotate the blade(s) side to side (Figure 53).
Measure between the outside cutting edges and
the flat surface (Figure 53). If both measurements
are not within 3/16 inch (5 mm), an adjustment is
required; continue with this procedure.

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. Park the machine on a level surface and disengage
the blade control switch.
2. Move the motion control levers to the brake position,
stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Check the air pressure of all four tires. If
needed, adjust to the recommended inflation;
refer to Checking the Tire Pressure in
Drive System Maintenance (page 34).
4. 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.
5. Measure the length of the rod extending out of
the adjusting block on the sides of the chassis
(Figure 55).
6. If the rod length is not a 3/4 inch (19 mm), remove
the hairpin cotter and washer from the end of the
adjusting rod (Figure 55) and turn the rod until the
3/4 inch (19 mm) dimension is obtained.
7. Install the end of the rod into the hole in the mower
mount and secure it with the washer and hairpin
cotter.
