ABSTRACT:
A slip hitch connection to a drive vehicle for a snow plow comprises an elongated flat planar member that can be hooked on to a connecting lug of the drive vehicle, the flat planar member being mounted on the snow plow frame for reciprocal movement in each of a pair of spaced apart coupling assemblies secured to the snow plow frame for connecting the snow plow to the drive vehicle. Each of the elongated flat planar members have an upper and lower elongated guide slot in which guide bolts that move up and down as the snow plow itself is moved up and down are received to enable the guide bolts and snow plow to which they are connected make limited reciprocal movement up and down while hooked up to the drive vehicle and being pushed forward during a snow plowing operation. This enables the snow plow to move rearwardly and upwardly enough to clear an object hit by the leading edge of the snow plow on the ground and then to reciprocate forwardly and downwardly to its original position after passing over the obstacle.
