I wonder given our general lack of agriculture in the state (hydroponics don't count) how experienced and capable any tractor shop is at servicing and repairing tractors vs. just selling parts.

I'd lean towards Kubota in that size, but that's based on what I've heard. I only have limited experience with the Kubota in that size and one of these days if I can find a reasonably clean older one when I have some spare coins I'd like to get one, though I'm thinking 30hp. Bigger deere's seem to be rock solid.
