Replacing Drive Belt - Toro Groundsmaster 220-D Service Manual

Replacing Drive Belt

The blade drive belt, tensioned by the stationary 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 cutting unit to the shop floor. Remove belt
covers from top of cutting unit and set covers aside.
2. Loosen flange nut securing idler pulley to deck.
Move pulley away from belt to release belt tension.
3. Remove carriage bolts and flange nuts securing
gear box plate to deck. Lift gear box plate and gear box
off deck and lay it on top of deck.
4. Remove old belt from around spindle pulleys and
idler pulley.
5. Route new belt around spindle pulleys and idler
pulley assembly, as shown in figure 18.
6. Reposition gear box plate on deck while routing belt
around gear box pulley. Mount gear box plate to deck
with carriage bolts and flange nuts previously removed.
7. Using approximately 50 lbs. of force, slide idler
pulley against belt.
8. Hold pulley in position and tighten nut.
9. Reinstall belt covers.
