ABSTRACT:
An improved adjustable mounting bracket for a moldboard snow plow includes a horizontal box beam, cross member which is attached by lugs to the back side of the plow and a third hitch connection which is attached to a bracket mounted on the box beam member. A support arm for a yoke fits over the mid-point of the box beam and is pivotally connected by a pin. The support arm is attached to a first frame member which overlays a second frame member mounted on the truck. The frame members are linked to one another and the first frame members may be moved vertically relative the second by an hydraulic cylinder. The construction is especially compact and lightweight.
