Trade in not so important to me as just being able to keep the tractor running. I've never had a problem big enough to actually need an independent mechanic until I got a Mahindra and then I owned it for 9 years before that happened.
Nearest dealers are Kubota/New Holland and JD, but the JD is a corporate chain store.
Most of the discussion has been about Kubota v the Korean manufacturers, but where does New Holland stand these days in relationship to Kubota, Kioti, and TYM in terms of reliability and parts support?
