Around 1967 Jerome Knudson, a young farmer in Crosby, North Dakota started building his own four-wheel drive tractors in his shop. When constructing these tractors Jerome used two steerable axels on a rigid frame with the front axel mounted on a separate framework, which allowed it to oscillate, or pivot, keeping all four wheels in contact with the ground when going over obstacles. When producing his tractors one of Jeromes main concerns included the cab of the tractor.  He was looking for a quieter more comfortable ride resulting in less fatigue and longer work days. He began by building the cab as a completely different structurer he then mounted it with rubber mounts to reduce vibrations and noise. He designed the seat with larger arm rest and even built the inside of the cab to be six and half feet tall allowing a farmer to stand up and stretch when needed.
