I was all dead set into buying an used tractor, except they all seem to be more expensive than the new one I ended up buying. I wasn't even looking at really low hour ones, because low hours over here is typically up to 1000 hours or so.
One tractor that I looked and stuck to my mind, was a New Holland TCE50 with 3000 hours and ball tires. They were asking €15000 for it. I paid about €2000 less than that for a new tractor. I liked this TCE50 because it was the typical European tractor, low profile, radial tires.
I was also interested on a low hour-ish Kubota, can't remember the model now, but no one in that Kubota dealer even bothered to lift their rear end out of the chair to even come talk to me, let alone showing the tractors.
