The 4000 series articulated tractors formed Massey Ferguson's big-tractor class of the 1970s and 1980s and competed directly, on the North American market, with the articulated models from Steiger, Versatile and Case; in Europe they stayed limited to large arable farms and contractors. In North America they went chiefly to large grain farms on the plains, where pulling power mattered more than manoeuvrability.
