• Physical stretching that prevents the belt tensioner from functioning within its specified range.

Installation Tips

• Ensure the engine is off and the spark plug wire is disconnected before service.
• Release the deck tensioner spring completely to provide enough slack for removal.
• Verify that all pulleys are free of debris and rotate smoothly before installing the new belt.
• Ensure the belt is properly seated in the V-grooves of all pulleys, including the deck spindles and the electric clutch.
• Cycle the blade engagement handle several times after installation to ensure proper belt seating.
