I own a Cub Cadet 1320 hydro with a 38" deck. The deck belt failed today and I"m looking thru the belts I have on hand and am wondering what 754-3029 is for. (someone hand marked 954-3029 on the package) From my notes (right or wrong): 954-3036 is for the deck (36"?) 754-3037 is for the hydro drive (unk"?) 954-3038 is for the PTO (38"?) cubcadet dot com is super slow to look up my own model. Looking up part numbers doesn't offer much description either. 754-3029 or 954-3029 just says 1/2" spindle belt with no length specified. Can anyone offer insight as to the prefix number change? is 754 the same as 954? thanks, rick iowa.
