PTO Belt Replacement - 50 Inch Deck

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 PTO belt if

any of these conditions are evident.

1. Park the machine on a level surface and disengage

the blade control switch.

2. Move the motion control levers outward to the

neutral lock position, set the parking brake, 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 3 inch (76 mm) height-of-

cut.

4. Remove the belt covers over the outside spindles.

5. If necessary, remove the oor pan to access the idler

pulley.

6. Using a spring tool, (Toro part no. 92-5771), remove

the idler spring from the deck hook to remove

tension on the idler pulley and roll the belt off of the

pulleys (Fig. 101).

WARNING

The spring is under tension when installed and can

cause personal injury.

Be careful when removing the belt.
