Adjusting the Front-to-Rear
Blade Slope
Check the front-to-rear blade slope any time you install the
mower. Before you check the slope, set the air pressure in
the front and rear tires to the recommended inflation; refer
to Checking the Tire Pressure on page 24. If the front of the
mower is not within a range of 1/8 to 3/8 in. (4 to 11 mm)
lower than the rear of the mower, adjust the blade slope
using the following instructions:
1. Park the tractor on a level surface.
2. Disengage the blades (PTO).
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. Disconnect the wire from the spark plug.
7. 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 on page 33.
8. Measure the length of the rod extending out of the front
of the adjusting block on the sides of the chassis
(Fig. 50).
