Abstract
An agricultural frame particularly for transporting active harrow elements and packer elements comprises a central frame section and a pair of wing frames projecting outwardly to the side of the central frame section at right angles thereto. The whole of the frame can be raised and lowered to lift the ground working implements from the ground. Each of the wing frames is rigid and is formed from a front beam and a rear beam interconnected by inclined beams carrying the active harrow elements. Each wing frame includes a steerable wheel at the outside end. Each wing frame is attached to the central frame by a rear pivot member which allows pivotal movement about a forward horizontal axis and also pivotal movement about a vertical axis for movement to the transport position. A latch is provided adjacent the front beam of the wing frame and is defined by a horizontal pin the axis of which defines the horizontal axis of pivotal movement of the wing frame. The latch pin is held in place within a receptacle of a hook member.
