Belt Maintenance

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.
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 will
prevent you from accidentally stripping the bolts free
of the retainers.
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. Lower the mower to the 76 mm (3 inch) height of cut.
4. Loosen the bottom bolt holding the mower-deck
curtain to the mower deck. Refer to
Mower-Deck Curtain (page
5. Remove the sheet metal guard. Refer to
Sheet-Metal Guard (page 33)
