Abstract
An implement attaching to a vehicle and having a work assembly and a linkage assembly, the work assembly having an edge commonly used for clearing snow. The work assembly may be for example a bucket on a front end loader. The linkage assembly is formed as a non-parallelogram quadrilateral with four pivot axes. Upper and lower pivot axes attach the linkage assembly to the work assembly. When the vehicle is driven so that the edge strikes an immovable object, the linkage assembly functions so that the lower pivot axis moves in a direction toward the work assembly relative to the upper pivot axis. That is, the quadrilateral linkage assembly functions to lift the edge as a heel of the work assembly remains on the ground such that the work assembly is allowed to tilt up so the edge can ride over the immovable object.
