Along the same thought as micahw. I have a 680 that had a 38" deck which I replaced with a 44C 44" deck. The belt, 954-3003A is a 5/8 by 89 1/2 is called for in all the parts diagrams, CC and Partstree. Went to my dealer got the belt and found the belt was too long. Even after adjusting the "J" hook, there was way too much slack. I compared the drive belt from the 38 deck and the 44 and found they were the same length, different part numbers though. The main pulley is 6 1/2" on the 38". On the 44" it's 5". My question is, were these decks equiped with different pulley's depending on the tractor they originaly were attatched to?
