My tractor with same hours has exact same problem. low and mid do not move but seem like in a bind, hi and neutral are both hi. What did your problem end up being? I can't figure it out.So my tractor only has 200 hours on it. While traveling down my driveway with no load on the machine it came to an instant stop. Now when in low and mid range the machine won’t move. When in neutral it seems like it is in high gear. High gear still works like it should. Has anyone had this happen? Or know what might have happened?
