WARNING:
Be sure to shut the engine off,
remove ignition key, disconnect the spark
plug wire(s) and ground against the engine to
prevent unintended starting before removing
the belt(s).
Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
Remove the belt guards by removing the self-
tapping screws that fasten them to the deck.
Grasp the rearmost portion of the PTO idler bracket
and pivot it toward the discharge chute to relieve
tension on the PTO belt.
Remove the PTO belt from around the engine
pulley (or electric PTO clutch) and from around the
PTO idler pulley(s).
Grasp the deck idler pulley and pivot it toward the
left to relieve tension on the deck belt.
Remove the deck belt from around all pulleys,
including the deck idler pulley.
Route the new belts (deck belt first) as shown in
Figure 17 and Figure 18.
