Hi, I noticed yesterday that my trans drive belt was worn I put the rig ( cub cadet 2010 rzt 54 25 hp Kawasaki Fh 721v) up on the ramps and cannot figure out how to get the new belt over the hydraulic line without disconnecting sit which I think I will have to dismantle half the tractor. Any help would help at this point. I'm happy to jroin this helpful forum. Thanks in advance for any suggestions. I searched the forums and came up empty.
