You need to make sure the 5075E isn’t poorly built. I’ve seen some that don’t even have the left sided collar shifter for forward and reverse. You have to clutch and go to and from reverse and the gear you were in. I would be annoyed by that.

The older Kubotas like the 6040 had an under built radiator and are prone to easily overheat. We’ve had 2 that do this. Not sure if they changed that.
