ABSTRACT:
A quick hitch-unhitch attachment for mounting a snow working implement on a vehicle, comprising a vehicle mount attachment (VMA) frame secured to the vehicle, has a pair of spaced sockets which are positioned below and behind the vehicle bumper when mounted on the vehicle. A first pair of reaction bearing surfaces are aligned with and to the rear of the spaced sockets and a transverse latch bar means extends transversely of the sockets. An intermediate support frame has a rearward end with a pair of latching arms extending in a rearward direction and in general alignment with the sockets, respectively. Each latching arm has a further reaction bearing surface for bearing against respective ones of the first pair of reaction bearing surfaces. A support frame has a forward end attached to the snow working implement and a rearward end pivotally connected to the intermediate frame for rotation about a horizontal axis. A latching mechanism on the intermediate support frame for positioning a latch member rearwardly of the transverse latch bar. A lift mechanism on the intermediate support frame pivots the support frame about the horizontal axis and lifts the support frame and working implement off the ground such that the weight thereof is borne by the reaction bearing surfaces and the pair of spaced socket means. A friction slide plate maintains the angular relationship between the intermediate frame and the support frame when the intermediate support frame is not coupled to the VMA frame.
