equivalent to 0.25 inch, while a single side is 0.125 inch
(Figure 55). Adjust the height of the mower deck to the
desired height.

blade slope; refer to Adjusting the Front-to-Rear Blade
Slope.
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 outward to the park
position, stop the engine, remove the key, and wait for
all moving parts to stop before leaving the operating
position.
3. Set the height-of-cut lever to middle position.
Note: Check and adjust the side-to-side blade level if
you have not checked the setting; refer to Side-to-Side
Leveling.
4. Carefully rotate the blades so they are facing front to
rear (Figure 56 ).
