摘要：
A finger plow includes an extension which may be extended or retracted to enable the finger plow to discharge snow and ice away from the wheels of the vehicle and to make a relatively wider snow cleared path while not unduly extending beyond the sidewalls of the wheels of the vehicle when not engaged in a plowing operation. The finger plow may be a one-way or reversible snow plow with one or two extensions. In the later case, the finger plow and one or more extension finger plows are rotatable relative to the chassis of the vehicle. Shear pins or a resilient mechanism may be provided to permit the finger plow to pivot rearwardly in the event that the finger plow extension encounters an obstacle.
