Abstract

An attachment assembly for attaching a snow plow blade to a vehicle includes a pair of interface brackets, a pair of articulated intermediate structures mounted to the interface brackets, a transversal member joining the intermediate structures, and a trigger assembly. The trigger assembly includes a static member with a pivoting attachment point for attachment to the snow plow blade and top and bottom attachment points for releasable attachment to the intermediate structure, a pin assembly, and a biasing means attached to the pin assembly and to the static member. The trigger assembly is biased toward a default position in which the pin member and the static member are at their closest. When applying a torque on the snow plow blade above a trigger threshold, the snow plow blade rotates from the default position to a triggered position.
