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).
The belt on your tractor is 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 a factory approved belt.
To change or replace the deck belt 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. 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 20.
5. Grasp the ratchet’s handle and pivot it toward the front
of the tractor to relieve tension on the belt.
6. With belt tension relieved, carefully remove the belt
from around the left-hand spindle pulley.
