Abstract
A frame for supporting an implement (e.g. a plow) on a vehicle is disclosed. The support frame extends longitudinally and generally comprises, at its rear end, a rear attachment mechanism for removably mounting the support frame to the underside of the vehicle, and at its front end, a front attachment assembly for supporting the implement. The frame comprises a rear section and a front section hingedly connected together such that the front section can pivot upwardly with respect to the rear section. The support frame also comprises a biasing assembly or mechanism, generally comprising a resilient member engaging the front and rear sections, such as to downwardly bias the front portion. By overcoming the downward bias of the biasing assembly, the front section can be further raised with respect to the ground surface, thereby providing greater clearance.
