Im looking at buying a 2004 john deere 4610. It has the hydrostat. Overall it looks like a nice machine that was taken care of but it has over 4000 hours. Owner has only owned it for a few hundred hours and is unsure if its had any motor or transmission work in the past. I've tried searching for other 4610s with that many hours to compare it too but I havent found any. Does anyone have a 4610 with that many hours? Have ya had to do any major work?
