Neighbor has a Case Farmall 65, same tractor I think. 2wd with a loader. Haven't spent a whole lot of time on it, but some.
His has the gear trans. I don't really like the gearing, low is too slow and high is too fast. A hydro would be way handier, especially for loader work.
It seems to do everything well for him, hasn't had much trouble with it, but it doesn't see a whole lot of use. All the filters are up front and pretty easy to service. A lot of small tractors have the hydro filter crammed up somewhere that's tough to get at.
