DRIVE BELT REPLACEMENT
(self-propelled models)
To remove drive belt:
1. Disconnect spark plug wire.
2. Set the right rear wheel to its lowest
cutting height, and the left rear wheel to

drive sheave, and finally, the engine
pulley (Figure 15).
4. Pull belt through opening under mower
pan and over blade.
5. Make sure the idler pulley turns and the
idler arm moves freely.

IMPORTANT: Be sure the belt seats in
sheave and pulley grooves with the idler
touching the back (flat) side of belt.
7. Adjust rear wheels to the same cutting
height.
