A detachable snow plow blade is driven by a skid-steer or other suitable vehicle. The detachable plow blade has hydraulically adjustable wing blades that each pivot under separate control about a main blade. Pins that support power cylinders between braces are arranged to enable each wing to extend through a range of motion from essentially perpendicular to and ahead of the main blade to essentially perpendicular to and behind the main blade. In a further alternative embodiment, the entire blade, including wing blades, may additionally be pivoted with respect to the vehicle, resulting in a very adjustable blade which is well adapted to emulate prior art box plow/pushers, conventional plows, pull back/drag plows, V-plows and fold-out plows.
