Replacing Drive Belt on Zero Turn Mower! DIY.

I've had this mower for several years now and this is the second time the drive belt needed replace. The first time I had some guy try and tell me it was something major and that the hydro stat was out. If anyone tells you that please check your drive belt! Much easier and cheaper fix if it's a drive belt and you can do it yourself. Who knows, some of these asshats will tell you it's the hydro stat, charge you a shit load and just change the drive belt. beware of scams! Anyways here is how to change the drive belt. These links are for parts for a rzt 50" cub cadet.
