The history of the WALKING FLOOR® unloader began nearly 70 years ago, when founder Keith Foster started an agricultural manufacturing company in Madras, Oregon USA. Today, the KEITH team designs, machines and fabricates nearly 100% of the components used in KEITH® WALKING FLOOR® systems. The company has sold more than 90,000 units around the globe and holds over 270 patents. KEITH is family owned company, still operated by the Foster family.
