There was a lot of food put on the table by JDs, FARMALLs, OLIVERs, and ALISS CHALMERSs tractors 60-70 years ago. If I understand this SCUT topic correctly, that is of little consequence.
A tractor with 26 X 12 - 12 rear tires (SCUT), and no position control on the three point hitch, would fall into a lesser category, like garden tractor or something like that. If the tractor has 27" or larger tires on the rear and still has no position control on the three point hitch, well then it just kind of falls in to the "not very easy to work with category".
