"AGRICULTURAL FRAME FOR PROPULSION OF GROUND WORKING IMPLEMENTS" ABSTRACT OF THE DISCLOSURE An agricultural implement for transporting particularly an active harrow element and packer element across the ground in both transport and working positions comprises a central frame and a pair of wing frames. Each wing frame includes a pair of parallel beams at right angles to the direction of working movement connected by inclined beams to which the harrow element is attached. The wing frame and the center frame can be raised into transport position by hydraulic action against the ground wheel axles. Each wing frame includes an outer wheel which in addition to the lifting movement can be twisted at right angles from the working direction to allow the wing frame to move into a transport position trailing behind the center section. The pivoting occurs about a pivot pin at the rear of and just inside the center section. A latch arrangement at the front of each wing frame latches the wing frame to the center section and also provides pivotal movement about a horizontal axis. The harrow element is preferably an active harrow including an elongate roller and a plurality of tines projecting out from the roller and inclined to radial a plane surrounding the axis of the roller.
