1. A snowthrower comprising:
an auger housing comprising spaced-apart first and second sidewalls connected to one another by a rear wall to define a front-facing collection opening, the rear wall comprising a lower edge, wherein the auger housing is supported upon a ground surface at least partially by first and second skids attached to the first and second sidewalls, respectively;
an auger positioned within the auger housing between the collection opening and the rear wall, the auger comprising:
an auger shaft comprising first and second end portions terminating at or near the first and second sidewalls, respectively, and defining an auger axis intersecting the first and second sidewalls, wherein the auger shaft is configured to rotate, relative to the auger housing, about the auger axis; and
a flight attached to the auger shaft, wherein the first and second skids are height-adjustable relative to the auger housing and are configured to support the auger housing upon the ground surface such that a surface of revolution defined by the flight is spaced-apart from the ground surface, during normal snowthrower operation, by an auger offset distance to create an auger clearance zone between the flight and the ground surface; and
a resilient scraper forming a cantilever having an upper end connected to the lower edge of the rear wall, the resilient scraper extending downwardly toward the ground surface and into the auger clearance zone to terminate at a lower end that is spaced-apart from the ground surface.
