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).
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.
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:
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.
Remove the belt keeper rod from around the
engine pulley.
Insert a 3/8”-drive ratchet wrench (set to loosen)
into the square hole found in the idler bracket on
the left side of the deck’s surface. See Figure 19.
Figure 19
Grasp the ratchet’s handle and pivot it toward the
front of the tractor to relieve tension on the belt.
With belt tension relieved, carefully remove the
belt from around the left-hand spindle pulley.
