I have a Hustler FasTrak 48" zero-turn with a 2 bag grass catcher made by Excel Industries, purchased brand new Sept. 2013. The belt came off the pulleys that run the blower unit. I have the Product Manual for the bagger, but it is basically useless. Confused...I'm a gal, but I am determined to get this belt back on without having to have my mower picked up by the dealer & into the shop for who knows how long.
