Inspecting the Belts

wear/cracks.
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.

blade-control switch.
2. Move the motion-control levers outward to the P
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 (38
mm (1-1/2 inches).
4. Remove the pulley covers.

remove the idler spring from the deck hook to remove
tension on the idler pulley and roll the belt off the
pulleys (Figure 58).

system.
