• Ensure the parking brake is engaged to stabilize the machine.
• Check the orientation of the V-belt to ensure it is seated properly in the pulley grooves.
• Verify the belt path follows the factory routing diagram found on the underside of the mower deck or in the owner's manual.
• After installation, manually rotate the pulleys to verify the belt is fully seated and does not jump the track.
