Applications
Snowblowers, to move snow towards an impeller, where it is thrown into the discharge chute. Combine harvesters use both enclosed and open augers to move the unthreshed crop into the threshing mechanism and to move the grain into and out of the machine's hopper. *Ice resurfacers use augers to remove loose ice particles from the surface of the ice. Plumbers use a plumber's snake, a flexible auger, to remove obstructions from pipes.
