I might be wrong, but the hydro is a Sunstran(spIJ) on either make. Sun Source is one of many nationwide dealers for them. That 2 speed rotor box is only gonna be found on a NH I'm afraid. JD
JD is right. NH quit using John deere transmissions back on the TR85_95 combines. I think the 2 speed rotor drive gearbox is the same on all of the later TR's but I'd have to look at a parts diagram to be sure. Might have started with TR96's.
