When to Replace

• Belt slips, causing inconsistent blade speed or poor cutting performance.
• Audible squealing or chirping from the deck area during operation.
• Blades fail to engage or stop spinning while the engine is running.

Installation Tips

• Before starting, disconnect the spark plug wire and engage the parking brake for safety.
• Lower the cutting deck to the lowest possible position to relieve tension.
• Take a photo or note the routing of the old belt around all pulleys before removal.
• Release the belt tensioner mechanism, typically an idler pulley on a spring-loaded arm.
• Remove the old belt and route the new belt according to your diagram or photo.
• Ensure the V-profile of the belt is seated correctly in each pulley groove.
• Re-engage the tensioner and verify the belt is taut and properly aligned.
