Slope (page 39)

.

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

).

5.

Measure from the tip of the front blade to the flat
surface and the tip of the rear blade to the flat surface
(

Figure 56

). If the front blade tip is not 1/16-5/16 inch

(1.6-7.9 mm) lower than the rear blade tip, adjust the
front locknut.

6.

To adjust the front-to-rear blade slope, rotate the
