Abstract
A plow assembly comprises a blade, structure attached to the blade and adapted to be attached to a vehicle for mounting the blade to and supporting the blade from the vehicle, and a wing attached to an end of the blade. The wing has a first portion mounted to the blade for translational movement relative thereto, and a second portion mounted to the first portion for rotational movement relative thereto. An actuator has a cylinder and first and second oppositely movable piston rods. The first piston rod and the cylinder operable to move the first portion of the wing relative to the blade, and the second piston rod and the cylinder are operable to move the second portion of the wing relative to the fist portion of the wing.
