Installing the Blade Drive Belt
1. Install the new blade drive belt around the blade pulley
and inside both of the belt guides (Fig. 41).
2. Adjust the belt guides so they are 1/8 in. (3 mm) away
from the pulley. Tighten the mounting bolts (Fig. 41).
Important Make sure that the left side belt guide is
very tight so that it does not move when the brake spring
pulls against it.
3. Install the mower; refer to Installing the Mower on
page 31.
Leveling the Mower from Side
to Side
The mower blade must be level from side to side. Check
the side-to-side level whenever you install the mower or
look for an uneven cut on your lawn. Before you level the
mower, set the air pressure in the tires to the recommended
level; refer to Checking the Tire Pressure on page 27.
1. Park the tractor on a level surface.
2. Disengage the blade (PTO).
3. Shift the ground speed lever into Neutral.
4. Set the parking brake.
5. Stop the engine and wait for all moving parts to stop.
6. Remove the ignition key.
7. Disconnect the wire from the spark plug.
8. Move the height-of-cut lever into the āCā notch.
9. Carefully rotate the blade side to side (Fig. 42).

12. Position the leveling bracket in a different hole and
install the washer and hairpin cotter (Fig. 43).
Note: Positioning the leveling bracket toward the front
hole lowers the blade height; positioning the leveling
bracket toward the rear hole raises the blade height.
13. Repeat steps 11 and 12 on the opposite side of the
mower.
14. Check the front-to-rear blade slope; refer to Adjusting
the Front-to-Rear Blade Slope on page 33.
Adjusting the Front-to-Rear
Blade Slope
Check the front-to-rear blade slope whenever you install
the mower. Before you check the slope, set the air pressure
in the tires to the recommended level; refer to Checking the
Tire Pressure on page 27. If the front of the mower is more
than 5/8 in. (16 mm) lower than the rear of the mower,
adjust the blade slope as follows:
1. Park the tractor on a level surface.
2. Disengage the blade (PTO).
3. Shift the ground speed lever into Neutral.
4. Set the parking brake.
5. Stop the engine and wait for all moving parts to stop.
6. Remove the ignition key.
7. Disconnect the wire from the spark plug.
