Just replaced my mower deck belt and thought I would like to share with you how to do it. After removing the deck from under the mower you will need to remove the center gearbox bracket that is on the discharge side of the mower so you can remove the old belt. Also loosen or remove the idler pulley so the belt can be turned sideways and slid under the pulley. See your dealer for a diagram of how the belt goes on the pulleys and reinstall the belt. Good luck.
