Mower Belt Maintenance

Inspecting the Belts
Service Interval: Every 25 hours—Check the belts
for 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.
1. Park the machine on a level surface and
disengage the blade-control switch.
2. Move the motion-control levers outward to the
P position, stop the engine, remove the
ARK
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 inch)].
4. Using a spring removal tool, (Toro part no.
92-5771), remove the idler spring from the deck
hook to remove tension on the idler pulley and
roll the belt off of the pulleys
WARNING
The spring is under tension when
installed and can cause personal injury.
Be careful when removing the belt.
