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.
All belt on your tractor are subject to wear and should be
replaced if any signs of wear are present.
IMPORTANT: The V-belt 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. Lower the deck by moving the deck lift lever into the
bottom notch on the right fender.
2. Remove the belt guards by removing the self-tapping
screws that fasten them to the deck.
3. Remove the belt keeper rod from around the engine
pulley.
4. On the 42-inch deck only, loosen but do not remove,
the idler pulley nuts. This will enable the belt to be
easily removed from the idler pulleys. See Fig. 6-7 on
the previous page.
