ABSTRACT:
There is provided an improvement in a device for mounting a plow blade onto the front of a motor vehicle. The mounting device includes a frame member having a forwardly facing, first end and a rearwardly facing second end, means for mounting the blade onto the first end of the frame member known as an A-frame and means for securing the A-frame at the second end onto the vehicle for pivotal movement about the first axis extending transversely across the front of the vehicle. This type of blade mounting device also includes a lift means for pivoting the A-frame or frame member upwardly about the first axis and against the weight of the plow blade to raise the plow blade from its plowing position. This lift means also allows the A-frame by the weight of the A-frame and plow blade to pivot downwardly into the lowered plowing position when desired. The improvement in this type of mounting arrangement is forming securing means between the A-frame and the vehicle as an intermediate link member or assembly which assembly is pivoted onto the A-frame at one end and onto the vehicle at the other end. The A-frame can and will pivot around the standard lifting axis as previously described until the blade is raised a limited amount. The link member or assembly has means for locking the link member or assembly with respect to the A-frame when the blade and A-frame are in their plowing positions to allow the vehicle to push the blade through the link member or assembly. This link member or assembly has a second position which is snapped into as the A-frame is tilted upwardly by the lift mechanism or means. In this second position, the front end of the A-frame is lowered to increase visibility of the driver and stability of the vehicle as it is operated with blade in the raised, non-plowing position.
