Abstract: This snowblower equipment includes a snowblower unit arranged to be readily and removably attached to the rear frame of a truck, and a truck so equipped, such that the rear frame or platform of the truck remains free for conventional trucking, either with or without the snowblower unit attached to it. This snowblower equipment includes a pivot section attached to the rear frame of a truck and at the edge of it, and having a lifting mechanism with upright pivots around which a second pivot section swivels bodily with the snowblower unit fixedly secured to it. The snowblower unit may thus selectively swivel between a lateral projecting position and a rearward projecting position relative to and outward of the rear frame.

Abstract: 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 packed 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.
