I'm not sure jdbnh is precisely right about case service being better than bobcat. So much depends on the dealer/service department. The John Deere, Kubota, M-F, and Bobcat dealers in southern NH all have pretty extensive and good service departments.
Of course we could put them all to the test and take similar model tractors, smash the same parts on all of them, call them up and see how long and how well they all take to fix them.
Anyone want to give me a quarter of a million to set up the test?
