A height adjustable snow plow mounting apparatus includes an elongated member having a snow plow mounting member positioned at each end thereof. A vehicle mounting member positioned on the elongated member engages a receiver on the motor vehicle for the purpose of releasably connecting the snow plow mounting apparatus to the vehicle. A support member comprising an extended sleeve which substantially spans the length of the elongated member functions to secure the vehicle mounting member to the elongated member. By simply reversing the position of the elongated member relative to the support member, the snow plow mounting members may be positioned above or below the horizontal plane of the vehicle mounting member. In turn, the apparatus readily supports two different heights of the vehicle mounting member relative to the motor vehicle, which heights are based upon standard height differences in motor vehicle ground clearance.
