Patent number: 5839516Abstract: A folding frame assembly is provided for supporting soil-cultivating equipment. The folding frame supports the soil-cultivators in a working position in which each cultivator is in contact with the field surface and a transport position in which each cultivator is not touching the field surface and the main wheels support most of the weight of the folding frame. The main wheels are retractable and can be moved from the transport position to an intermediate position for working the field surface. The folding frame assembly includes a support frame, a main frame, and two wing frames. The wing frames are pivotally connected to the main frame and the main frame is pivotally connected to the support frame. Hydraulic cylinders can be used to fold the wing frames and the main frames to their respective positions to that the folding frame assembly is in the transport position or unfold the main and wing frames so that the folding frame assembly is in the working position.Type: GrantFiled: April 14, 1997Date of Patent: November 24, 1998Assignee: Unverferth Manufacturing Co., Inc.Inventors: Loren G.
