How do you change the belt on a Cub Cadet lawn mower?

what model and which belt? If it is a 1000 series you have a transmission drive belt and a deck belt. I you have a 2000 series or higher or a cub cadet with an IH logo then you only have one belt the deck belt and no drive belt you have a drive shaft. So the model of the tractor and what belt needs to be given before the correct answer can be given.
