Belt Maintenance

Replacing the Mower Deck
Belt
Service Interval: Every 100 hours—Check the mower
deck belt.
Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks and cracks
are signs of a worn deck belt. Replace the deck 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 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. Loosen the bolts and remove the belt covers with the
bolts attached to them.
4. Loosen the front idler pulley by loosening the nut.
5. Remove the worn mower belt (Figure 65).
6. Install the new mower belt around the deck pulleys
and clutch pulley (Figure 65 ).
7. Using a ratchet in the idler arm, tighten the idler
pulley until the spring is stretched 6-1/2 inches (165
mm) from hook to hook (Figure 65 ).
8. Tighten the front idler pulley by tightening the nut.
9. Install the belt covers onto the cutting unit and
secure the bolts.
