ABSTRACT:
A coupling for a plow which includes push beam which is attachable to the front of a vehicle and a supporting frame which is attachable to the back side of the plow. The push beam has at least one forwardly extending arm at each end of the beam and a transversely extending connecting pin for each arm. The supporting frame has a pair of rearwardly extending arms. The coupling also includes a slotted mounting tab which is attached to the rearward end of each rearwardly extending arm for receiving the pins and a retaining rod which is removably attached to the tabs for blocking the downward movement of the forwardly-extending arms and preventing the pins from moving out of the slots in the tabs.
