Please help me to replace the deck belt on a john deere 130. Thank you!

Start by lowering the deck all of the way and then removing the drive belt from the engine shaft. There are pulleys, one for each blade and then a spring loaded tensioner that must be retracted to give you slack to remove the belt. Keeper pins help keep the belt from jumping off the pulleys, you must peel the belt between the pin and the pulley. http://images.google.com/images?hl=en&q=john+deere+belt+diagram&um=1&ie=UTF-8&ei=nP4bStTABojGM6DoiJcP&sa=X&oi=image_result_group&resnum=1&ct=title
