When to Replace

• Loss of tension resulting in slippage during heavy cutting loads
• Evidence of glazing (shiny or slick appearance) on the inner v-groove surfaces
• Excessive stretching that prevents the tensioner from maintaining proper pressure
• Deep gouges or missing segments caused by debris interference

Installation Tips

• Disconnect the spark plug wire before beginning installation to prevent accidental engine start.
• Ensure the mower deck is fully lowered or removed according to the owner's manual for better access.
• Loosen the belt tensioning hardware fully before attempting to remove the old belt.
• Clean all pulleys of dirt, grass, and oil residue before installing the new belt to ensure proper seating.
• Verify that the belt is correctly routed through all guides and pulleys before applying final tension.
• Run the mower at low throttle for several minutes after installation to seat the belt into the pulley grooves.
