Changing the Deck Belt & PTO 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 and PTO 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. 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 26.
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.
IMPORTANT: Carefully allow the ratchet to pivot rearward
before removing it from the square hole.
7. Remove the deck belt from around all pulleys, including
the deck idler pulley.
8. Route the new belts as shown in and Figure 27 and 28.
9. Remount the belt guards removed earlier.
