Unverferth Manufacturing Company, Inc. has been serving America's farm operations since 1948. We began with the manufacture and marketing of dual and triple wheel systems and components. The impact of this innovation is evident today on over 90% of North American farms and since expanded into the world market. Unverferth is a leading manufacturer and marketer of tillage equipment, pull-type sprayers, fertilizer applicators, hay and grain handling equipment, and agricultural dual and specialty wheels. The family owned atmosphere which promotes pride in product quality and value is as prevalent today as it was over 65 years ago.
