I own my second Kubota for 6 months now. On the first tractor (a B2320), I stopped in at the dealer and was kidding the salesman, saying something like "if the tractor is so good, why is it warrantied for only one year". He smiled and said "Go home and try to break it". I worked that machine pretty hard but also maintained it. Second is a B2650, good machine so far.
I have also told many people that if the dealer had told me the tractor would do stuff that I did with my tractor I would have called him a liar. Never shopped for Green, just a preference.
