NOTE:
Several components must be removed and
special tools (i.e. air/impact wrench) in order to change

Changing the Deck Belt
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).
All belts on your tractor are subject to wear and should
be replaced if any signs of wear are present.
IMPORTANT
: The V-belts found on your tractor are
specially designed to engage and disengage safely. A
substitute (non-OEM) V-belt can be dangerous by not
disengaging completely. For a proper working machine,
use factory approved belts.
To change or replace the deck belt on your tractor,
proceed as follows:
1. Remove the belt keeper rod(s) from around the
engine pulley.
2. Remove the cutting deck as instructed earlier in this
section.
3. Remove the belt guards by removing the self-tapping
screws that fasten them to the deck.
4. Carefully loosen, but do not remove, the deck idler
pulleys.
5. Remove the deck belt from around all pulleys,
including the deck idler pulleys and the electric PTO
clutch (units with electric PTO).
6. Route the new belt as shown in Fig. 6-7 and retighten
the deck idler pulleys.
7. Reinstall the belt guards removed earlier and
remount the deck to the tractor.
8. Route the belt around the engine pulley and reinstall
the belt keeper rod(s).
WARNING:
Avoid the possibility of a
pinching injury. Do not place your fingers
on the idler spring or between the belt
and a pulley while removing the belt.
