Removing the Mower Belt
Squealing when the belt is rotating, blades slipping when
cutting grass, frayed belt edges, burn marks and cracks are

these conditions is evident.

motion control levers to the neutral locked position
and set the parking brake.

parts to stop before leaving the operating position.
3. Lower the mower to the 3 inch (76 mm) height-of-cut
position.
