Replacing the Mower Belt

The signs of a worn mower belt are squealing while the
belt is rotating, blades slipping while you are cutting
grass, frayed belt edges, burn marks, and cracks. Replace
the mower belt if you detect any of these signs.
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. Remove the belt covers over the outside spindles.
4. Loosen the fixed idler arm and adjust it to relieve the
belt tension on the fixed idler pulley (Figure 49).
