Installation Tips

• Disconnect the spark plug wire before beginning installation to ensure safety
• Remove the deck from the mower for easier access to pulleys
• Loosen the belt tensioner mechanism to provide enough slack for removal
• Clean debris from the pulley grooves before installing the new belt
• Verify the belt is properly seated in all pulley grooves before applying tension
