Jerome Knudson developed crab-steer and self-leveling tractors suiting to farm the hillside land of North Dakota. Knudson manufactured several models (with a green and white paint scheme) in North Dakota before selling the rights to Allmand Brothers Inc. Allmand resumed production of Knudson tractors in Nebraska (using yellow paint)until 1983.
