Abstract: An auger housing as part of a snowthrower or part of a snowthrower implement for attachment with a vehicle. The auger housing may include a rear wall and spaced-apart first and second sidewalls connected to one another by the rear wall to define a front-facing collection opening. The rear wall may define a lower edge extending between the first and second sidewalls along a transverse direction. The auger housing may also include an oscillating scraper connected to the lower edge of the rear wall. The oscillating scraper extends downwardly from the lower edge toward a ground surface and is configured to move relative to the rear wall in a reciprocating motion.

Abstract: A hand-held debris blower including a blower tube and an associated ejector. The blower includes an airflow generator adapted to generate a primary airflow that is directed into a blower tube. A flow ejector is operable to selectively increase a working airflow provided by the blower by selectively entraining a secondary airflow within the primary airflow.
