Mower Belt Maintenance
Inspecting the Belts
Service Interval: Every 25 hours—Check the belts for wear
or cracks.
Check the belts for cracks, frayed edges, burn marks, or any
other damage. Replace damaged belts.
Replacing the Mower Belt
The signs of a worn belt include squealing while the belt is
rotating, blades slipping while cutting grass, and frayed edges,
burn marks, and cracks on the 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 switch.
2. Move the motion-control levers outward to the PARK
position, shut off 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 the lowest cutting position of
38 mm (1-1/2 inches).
4. Remove the pulley covers (Figure 65).

remove the idler spring from the deck hook to remove
tension on the idler pulley, and roll the belt off the
pulleys (Figure 66).
WARNING
The spring is under tension when installed
and can cause personal injury.
Be careful when removing the belt.
