As far as I know (and there are always exceptions), for the most part that all inner change. Are far as rear attachments, if it is a three point, then anything category 0 will work. If you have the movable drawbar, then the same attachments that fit on the PK will work. The mower decks are the same, however, the hitch for the deck may be different. There isn't much that was offered that was specific for the Jim Dandy.
