Ok what is /does ISO mean/stand for? I wish that there was a key. And how about horse power or some other information about your tractor beyond the model numbers. I am always wondering or searching the web to figure out what sort of scale is being talked about. Wish that all tractors were as clear as my TC35A. A 35HP tractor. New Holland has relabeled it again, I don't even know what the new label is.
Thanks Boatyard
