Snow plow having a pneumatic lifting device for reducing the wear on the blade of the snow plow

摘要

A snow plow lifting device is operatively connected to a snow plow for selectively imparting a lifting force on the snow plow. This lifting force reduces the effective weight of the snow plow bearing on an underlying surface such as a roadway. Thus, during a snow plowing operation, this reduces the wear on a lower edge of a blade that forms a part of the snow plow.
