Adjusting the Front-to-Rear
Blade Slope
Check the front-to-rear blade level any time you install the

(7.9 mm) lower than the rear of the mower, adjust the blade
level using the following instructions:

Park the machine on a level surface and disengage the
blade control (PTO).
Move the motion control levers to the brake position,
stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
Check the air pressure of all four tires. If needed, adjust
to the recommended inflation; refer to Checking the
Tire Pressure, page 28.
Check and adjust the side-to-side blade level if you
have not checked the setting; refer to Leveling the
Mower from Side-to-Side page 28.
Measure the length of the rod extending out of the
adjusting block on the sides of the chassis (Fig. 39).
If the rod length is not a 3/4 inch (19 ram), remove the
hairpin cotter and washer from the end of the adjusting
rod (Fig. 39) and turn the rod until the 3/4 inch (19 mm)
dimension is obtained.
.
Install the end of the rod into the hole in the mower
mount and secure it with the washer and hairpin cotter.
Repeat steps 5 through 7 for the opposite side of the
mower.
