 he applied his engineering and farming knowledge to finding a better way to harvest the fertile but often steep slopes found in that area.

In 1941 Hanson conceived of the self-leveling control for hillside combines
Combine harvester
The combine harvester, or simply combine, is a machine that harvests grain crops. The name derives from the fact that it combines three separate operations, reaping, threshing, and winnowing, into a single process. Among the crops harvested with a combine are wheat, oats, rye, barley, corn ,...

, and by 1945 the first self leveling mechanisms were built.

Hanson founded the RAHCO Company to build self-leveling mechanisms and since then, RAHCO of Spokane, Washington has grown into a world leader in the design and production of custom commercial machinery systems. RAHCO estimates that automatic leveling has saved at least three percent of grain harvested on lands where combine leveling is needed, which is worth millions of dollars each year.

After the self-leveling control for hillside combines, Hanson began adapting the ideas and principles he had developed into a wide variety of construction machines used for canal, highway, dam, and airport construction. He went on to found a company that became a world leader in the design and production of custom commercial machinery, including the largest canal finishing machinery in the world for the California aqueduct, the world's largest 2,000 ton gantry crane used in the Grand Coulee Dam
