Belt Maintenance

Inspecting the Belts

Service Interval: Every 50 hours
Replace the belt if it is worn. The signs of a worn belt
include squealing while the belt is rotating; the blades
slipping while cutting grass; and frayed edges, burn
marks, and cracks on the belt.

Replacing the Mower Belt

Important:
The fasteners on the covers of this
machine are designed to remain on the cover
after removal. Loosen all of the fasteners on
each cover a few turns so that the cover is loose
but still attached, then go back and loosen them
until the cover comes free. This prevents you
from accidentally stripping the bolts free of the
retainers.
1. Disengage the PTO, move the motion-control
levers to the N
parking brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Lower the mower to the 76 mm (3 inch) height
of cut.

curtain to the mower deck. Refer to
the Mower-Deck Curtain (page
