Adjusting the Front-to-Rear Blade
Slope
Check the front-to-rear blade slope any time you install the
mower. If the front of the mower is more than 7.9 mm
(5/16 inch) 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. Engage the parking brake, shut off 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 Leveling
from Side to Side (page 38) .
4. Carefully rotate the blades so they are facing front to
rear (
