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 (PTO).
2. 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.
3. Check the air pressure of all four tires. If
needed, adjust to the recommended inflation;
refer to Checking the Tire Pressure in
Drive System Maintenance, page 29.
4. 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.
5. Measure the length of the rod extending out of
the adjusting block on the sides of the chassis
(Figure 46 ).
6. If the rod length is not a 3/4 inch (19 mm), remove
the hairpin cotter and washer from the end of the
adjusting rod (Figure 46 ) and turn the rod until the
3/4 inch (19 mm) dimension is obtained.
7. Install the end of the rod into the hole in the
mower mount and secure it with the washer and
hairpin cotter.

and carefully rotate the blades so they are facing

surface and the tip of the rear blade to the flat
surface (Figure 47 ). If the front blade tip is not
1/16-5/16 inch (1.6-7.9 mm) lower than the rear
