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
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, disengage
the blade-control switch (PTO), and engage the
parking brake.
2. 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 the 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 44) .
4. Carefully rotate the blade(s) so they are facing
front to rear (
Figure 56 ).
