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 (Fig. 42).
Note: After adjusting the adjustment nuts, make sure there
is no slack in either support rod (Fig. 44). Tighten either
one to remove the slack (Fig. 42).

13. When the front-to-rear blade slope is correct, tighten the
lock nuts and check the side-to-side level of the mower;
refer to Leveling the Mower from Side-to-Side,
page 28.
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.
