ABSTRACT:
A multiple implement folding hitch designed to permit a plurality of implements to be pulled in a side-by-side relationship during field operations and adapted to permit the effective width of the implements to be reduced for transport purposes. The hitch comprises a transversely extending frame comprising a plurality of frame members pivotally secured together in an end-to-end relationship. First and second spaced apart trailing implements are operatively secured to opposite ends of the frame. A first tubular member extends forwardly from the transversely extending frame and has its forward end adapted to be connected to the prime mover. A second tubular member is telescopically received by the rearward end of the first tubular member and has a third trailing implement connected thereto which is positioned between the first and second implements. First and second elongated members are pivotally connected at their forward ends to the first tubular member and extend rearwardly and outwardly therefrom. The rearward ends of the elongated members are pivotally secured to the transversely extending frame adjacent the outer ends thereof. Hydraulic cylinders interconnect the tubular member and the elongated members to cause the transversely extending frame to be moved from a field position to a folded transport position. The second tubular member is selectively slidably moved rearwardly with respect to the first tubular member so that the trailing implement connected thereto may be moved rearwardly with respect to the implements connected to the tranversely extending frame when the frame is moved to its folded transport position so that the overall width of the apparatus is reduced.
