When to Replace

• Excessive stretching that prevents the tensioning system from maintaining firm contact.
• Evidence of glazing (shiny or smooth surface) caused by chronic belt slippage.

Installation Tips

• Disconnect the spark plug wire before beginning installation to ensure the engine cannot start.
• Engage the parking brake and lower the mower deck to the lowest position for easier access.
• Remove deck covers to clear debris from pulleys before routing the new belt.
• Follow the routing diagram located on the mower deck decal to ensure correct pulley engagement.
• Verify that the belt is properly seated in all pulley grooves before tensioning the spring-loaded idler arm.
