Components of the Belt System
- Engine pulley: Spins the belt when the engine runs.
- Driven pulley: Connects to the drive wheels.
- Belt: Loops around both pulleys, transferring power.
- Guide and tension pulleys: Keep the belt aligned and tight.

Removing the Old Belt
- Slide the belt off the pulleys, noting its routing path.
- If needed, take a photo or draw a diagram to remember the belt’s position.
- Inspect the pulleys for wear or damage while the belt is off.
Installing the New Belt
- Place the new belt onto the pulleys following the previous routing, or refer to the diagram you made.
- Ensure the belt seats properly in all pulley grooves.
- Reattach the tension pulley and tighten it to apply the correct tension.
Checking the Belt Tension and Alignment
Proper tension ensures the belt does not slip or wear prematurely.
It should be snug but not overly tight; refer to your owner’s manual for specific tension settings.
Run the mower briefly to check if the belt moves smoothly, and listen for unusual noises.
Reassembling the Mower
Replace the outer cover carefully, ensuring all bolts are tightened securely.
Reconnect the spark plug wire and perform a test run to verify proper operation.
If the mower moves smoothly without slipping or noise, the belt replacement is successful.
