An improved scraping edge for use on a plow blade employing at least one resilient scraping edge section for contact with a surface to be plowed and mounting holes to attach the scraping edge section to the plow blade.

Material, pusher with modular composite scraping edge

An improved material pusher or containment plow employing a floating vehicle-coupling system, a wear shoe, as well as a plurality of removable scraping edge sections.

Material pusher with floating coupler

An improved material pusher or containment plow employing a floating vehicle-coupling system, a modular composite scraping edge, a front-pivoting wear shoe with an adjustable angle, as well as water-shedding features. The disclosed containment plow and features are provide improved the surface outcome under various snow and ice conditions.

A material pushing apparatus is disclosed that has a central blade, at least one removable side plate attached to the central blade and a segmented scraping edge flexibly attached to the central blade along the bottom longitudinal edge of the blade. A position sensor is attached between the blade and the scraping edge and produces a position signal that is displayed to indicate the relative position between the blade and edge in order to characterize the amount of downward pressure applied to the scraping edge. Other aspects and features of the disclosed apparatus include a tilt sensor and display, and an improved coupler having shock-absorbing features and a cam-type clamping arrangement.
