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.
