Belt Maintenance

Inspecting the Belts

Service Interval: Every 100 hours—Inspect all belts
for cracks and wear.
Check belts for cracks, frayed edges, burn marks or any
other damage. Replace damaged belts.

Replacing the Mower Belt

The signs of a worn mower belt are squealing while the
belt is rotating, blades slipping while you are cutting
grass, frayed belt edges, burn marks, and cracks. Replace
the mower belt if you detect any of these signs.
1. Disengage the PTO, move the motion control levers
to the neutral locked position, and set the parking
brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Remove 2 bolts and washers in each belt cover and
remove the belt covers over the outside spindles
(Figure 45).
4. Pull on the idler arm to relieve the belt tension on
the left spindle pulley (Figure 43 or Figure 44).
5. Remove the old belt.
6. Install the new belt around the pulleys (Figure 43
or Figure 44).
7. Install the belt onto the spring loaded idler pulley.
