Installation Tips

• Disengage the spark plug wire before beginning installation to ensure the engine cannot start.
• Loosen the deck tensioning mechanism to provide necessary slack for belt removal and installation.
• Clean the pulleys of debris and grass buildup before installing the new belt.
• Ensure the belt is properly seated in all pulley grooves before applying final tension.
• Run the mower deck at low speed for several minutes after installation to ensure proper alignment and seating.
