A method and apparatus for removing snow from roadways and the like includes the provision of a curved scraper blade having top and bottom edges and defining a generally circular passageway forward of the blade extending longitudinally the length of the blade. Forward movement of the blade causes the bottom edge to lift up snow from the roadway and as it is urged into the passageway, pressurized air from an air blower is expelled into the passageway, causing the snow therein to be expelled laterally of the scraper blade and over the roadside. The pressurized air may be expelled into the passageway through one or more apertures in the blade intermediate its ends or alternatively, through an aperture at either end of the blade. An extendible top blade on the scraper blade permits variation of the overall blade and passageway configuration to accommodate different snow conditions while the scraper blade is angularly displaceable about a central vertical axis to alter the lateral discharge path of expelled snow from the passageway.
