I'm trying to find a replacement deck for the old 48C currently on my 325. Have been scouring the adds and found a few that look like they might fit, but I don't have any cross reference to check against. Just called the local JD dealer and was told that there is no cross reference of any kind. The only info they had was the three part numbers for the original 325 decks ( the 48", 48C and the 54"). I have always been under the impression that at least some of JD's other model's decks could be used. I checked a tractor data site and found the original mower attachment options but no info on compatible decks. Does anybody know if there is a cross reference chart available somewhere? I find it hard to believe that the JD dealer wouldn't be able to cross reference something like that.
