Abstract

A snow plow cutting edge, including at least one elongate backing plate removably fastened to a lower edge of a snow plow moldboard or to a cutting edge trip mechanism. The elongate backing plate has a long axis and a plurality of biasing member engaging structures. Slide bars are engaged to the elongate backing plate. The slide bars are arranged proximate one another along the long axis of the elongate backing plate and are slidable generally perpendicular to the long axis. Biasing members are engaged between the biasing member engaging structures and the slide bars such that the slide bars are biased generally perpendicular to the long axis toward a surface to be cleared of snow. Replaceable cutting edge sections are removably attached to one of the plurality of slide bars and located adjacent at least one of the other replaceable cutting edge sections.
