ABSTRACT:
A digging implement, for example, a snowthrower has a casing with a discharge from the casing and a coiled blade mounted in the casing on a lateral shaft. The blade is arranged for advancement sideways into a body of particulate material, e.g. snow. The blade shaft also carries a pair of discs attached to the shaft at opposite ends of the blade, with each of the discs having a cutting edge portion formed into radial corrugations. The discs cut kerfs in the snow at either end of the blade and reduce the power required to advance the implement into the material being removed.
