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.

Abstract: A steering knuckle to be used with the steering assembly of a vehicle such as a farming tractor is disclosed. The steering knuckle comprises several preconfigured attachment areas where attachment element(s) or bracket(s) can be releasably yet rigidly secured. The attachment areas may be further reinforced with additional knuckle material (e.g. metal, metallic alloy). The steering knuckle therefore provides predetermined and preconfigured attachment locations where a wheel-replacing track system can be secured, thereby allowing the track system to be mounted to the vehicle while avoiding attachment at inconvenient or weak locations.

Abstract: A track system configured to be mounted to a vehicle comprises a drive wheel, a frame assembly, front and rear idler wheels respectively pivotally mounted at the front and rear extremities of the track system, road wheels pivotally mounted along the length of the track system, between the front and rear idler wheels, and an endless traction band disposed about the drive wheel, the idler wheels and the road wheels. The idler wheels and the road wheels are pivotally mounted on tandem frames such that adjacent tandem frames are overlapping. The tandem frames are pivotally mounted to the frame assembly via longitudinally spaced pivoting points.
