ABSTRACT OF THE DISCLOSURE A snowblower and a scarifying auger assembly for it which are characterized by a helicoid auger provided with scarifying teeth serially secured along its outer helical edge and each pivotally restrained by a shear bolt to scarify and easily plow and blow away the picked snow and for pivotal retraction of any tooth upon impact with an obstacle. The helicoid auger is thus relatively of essentially smaller diameter and protected by the scarifying teeth against impact of obstacles against it and against the ensuing expensive repair. Snow-throwing scoops are also arranged to be attached in different numbers and positions around the rotation axis of the helicoid auger.
