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.
