ABSTRACT:
Coupling for a plow comprising, a pair of mounting tabs which are fixed to the rearward ends of a pair of arms which form part of a supporting frame for a plow. Each tab comprises a flat plate which includes an opening at the rear edge, a first slot which extends forwardly from the opening and which terminates in a forward edge and a second slot which extends rearwardly from the forward end of the first slot and which terminates in a rearward edge. The opening is adapted to receive a connecting pin of a push beam which is attached to the plow vehicle. The first slot is adapted to receive the pin, so that the pin rests against the forward edge when the plow is pushed forwardly by the plow vehicle. The second slot is adapted to receive the pin from the first slot so that the pin rests against the rearward edge when the plow is being pulled rearwardly by the plow vehicle. The invention also comprises a mounting tab such as that described above which is adapted to be mounted to a conventional plow supporting frame.
