Have driven rented Kubotas a number of times, with no problems. Not enough experience to base a purchase decision on, but you might talk to the people in the rental business. None of the rental places in Oklahoma rent JD that I am aware of.
I own a new JD, and have had no problems so far. Again, not enough experience to base a purchase decision on. But, it is made in the good old USA and parts are readily available.
