A pusher for snow or other material includes a blade including a front surface for moving material and an opposite rear surface, and upper and lower edges. A wiper is secured to the lower edge of the blade. Left and right sidewalls are connected to opposite sides of the blade. The sidewalls are each arranged transverse to the blade and define chain-engaging apertures. Left and right skid-shoe assemblies are connected respectively to the left and right sidewalls and slidably support the blade above a surface to be cleared. A plurality of cross-supports are connected to the rear surface of the blade and extending between the left and right sidewalls. A coupler structure is connected to the rear face of the pusher and defines a pick-up location adapted to be engaged by an associated pusher-moving machine for operative connection of the blade to the pusher-moving machine.
