I'm pretty sure only the very recent ones are MTD. I could be wrong though. But with my experience, and the GreenHornet's experience with the Sabre (made by JD), John Deere machines are very complex and not really worth all the hype. And to be honest, mine didnt mow very well when I parked it. I would much rather have a craftsman. Just my opinion, maybe I got a bad one...?
