ABSTRACT:
A plow wing for mounting on each side of a snow plow blade and adjustable by the snow plow operator to permit the snow pushed by a plow to move in a direction determined by the operator. When not in use, the wings are retracted rearward so that they will not interfere with normal plowing. The purpose of the wings is to prevent the accumulation of snow in an area which must be cleared, such as walls and sides of bridges abutting traffic lanes and driveways. The plow blade is driven hydraulically and the wings are connected to said plow blades by mating L-shaped members. One set of cables and springs is used to move each wing to its non-operative position. A second set of cables, springs and pulleys serves to move either or both wings to their operative position under the control of the plow operator.
