About Acculevel-Ag Systems

In 1946 Raymond Hanson the son of a Palouse farmer, invented and patented the level sensing mercury switch. This led to the improved grain harvesting and productivity in the steep terrain of Eastern Washington, famous for its wheat crops. These slopes can range up to 45 percent slope.

Three generations later, the Hanson family still manages the agriculture division of Hanson Worldwide LLC for Acculevel Ag. Systems.  Together with our business partners at Arrow Machinery, we provide the parts, service, engineering and marketing for all of North America’s sloping farmland.

We have been John Deere’s authorized supplier since 1986. Our products provide the performance, reliability and safety required for hillside and sidehill operations. We meet or exceed all the safety requirements of John Deere, U.S. Tire and Rim association, as well as industry standards for hydraulics and steel structure.
