A plow adapter for use in conjunction with a vehicle allows the plow to be alternately used in two modes of operation: floating or rigid. The adapter comprises illustratively first and second members each having one end pivotally connected, respectively, to the plow frame and the vehicle frame, the other ends of the members are slidably engaged to permit floating operation in which the plow follows the contours of the road surface. In addition, one of the members is provided with a releasable locking member which can be adapted to fix the relative positions of the first and second members with respect to one another, thereby permitting rigid operation in which downward pressure exerted through the adapter forces the plow against the road surface for such operations as scraping.
