In 1941, near Palouse, Washington, Raymond A. Hanson conceived of a self-leveling mechanism for hillside combines. On the steep hills in the Pacific Northwest, leveling is necessary to save grain because of the gravity grain separation mechanism. Before the Hanson invention, manual leveling required a person to stand on the combine platform and adjust the machine to the lay of the land - a hot, tedious job. The grain-saving attributes of Hanson's invention were probably more important than the labor saving, although both were valuable.
