• Audible squealing from the deck during operation.
• Scheduled replacement as recommended by the manufacturer's service interval.

Installation Tips

• Disconnect the spark plug wire before performing any maintenance.
• Lower the mower deck to its lowest position to relieve belt tension.
• Document or photograph the belt's routing path around all pulleys before removal.
• Ensure all pulleys are clean, free of debris, and spin freely.
• Confirm the new belt is properly seated in all pulley grooves before re-engaging tension.
