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 machine on level ground, disengage the blade
control switch, engage the parking brake, stop
engine, and remove key. Wait for all moving parts
to stop before leaving the operator's position.
2. 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.
3. Carefully rotate the blades so they are facing front
to rear (Figure 71 and Figure 72).
