the front-to-rear slope again. Continue adjusting
the nuts until the front blade tip is 1/16–5/16 inch
(1.6–7.9 mm) lower than the rear blade tip (Figure
107).
Note: After adjusting the adjustment nuts, make sure
there is no slack in either support rod (Figure 109).
Tighten either one to remove the slack (Figure 107).

tighten the locknuts and check the side-to-side
level of the mower; refer to “Leveling the Mower
from Side-to-Side” on page 6 - 8.
Inspecting the Belts
Inspect all belts every 100 hours.
Check the belts for cracks, frayed edges, burn marks,
or any other damage. Replace damaged belts.
Replacing the Mower Belt
Squealing when the belt is rotating, blades slipping
when cutting grass, frayed belt edges, burn marks, and
cracks are signs of a worn mower belt. Replace the
mower belt if any of these conditions are evident.
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. Set the height-of-cut at A [1-1/2 inch (38 mm)].
4. Remove the belt covers over the outside spindles.
5. Pull the idler pulley in the direction shown in
Figure 108 and roll the belt off of the pulleys.
6. Route the new belt around the engine pulley and
mower pulleys (Figure 108).
7. Pull the idler pulley in the direction shown in
Figure 108 and route the belt onto the idler pulley
(Figure 108).
8. Rotate the belt guide toward the pulley until it
stops on the idler arm (Figure 108).
