Replacing the Drive Belt

The blade drive belt, tensioned by the spring loaded idler

pulley, is very durable. However, after many hours of use,

the belt will show signs of wear. Signs of a worn belt are:

squealing when belt is rotating, blades slipping when

cutting grass, frayed edges, burn marks and cracks. Replace

the belt if any of these conditions are evident.

1. Lower the cutting unit to the shop floor. Remove the

belt covers from the top of the cutting unit and set the

covers aside.

2. Using a torque wrench or similar tool, move the idler

pulley (Fig. 33) away from the drive belt to release the

belt tension and allow the belt to be slipped off the

gearbox pulley (Fig. 34).
