i thank you all for your feedback i did look at the 44in deck and seen the diagram and all the pulleys are in the same pattern but wasnt sure if it would work but will try it this weekend thanks again.
its a 54 in deck, on the parts diagram it does not show a belt i do believe its a 3184 or something like that im really not that familiar with cub my father in law is disabled so i do all the work on his two cubs. which by now i should be an expert.
does anyone have a pic or diagram of how the belt goes on this deck my father in law has this tractor and somehow the serial number sticker has been power washed off and cub cadets parts diagrams really suck
