Abstract: An improved snowthrower is disclosed having a body with a front housing containing a power driven auger continuously engaged with the ground for propelling the snowthrower forward, and a bottom scraper edge carried by a rear wall of the housing biased for continuous resilient engagement with the ground. In a preferred embodiment, the housing is pivotally connected to the snowthrower body by a fixed mounting bracket and springs connected to the housing and mounting bracket pivotally urge the housing such that the scraper edge is biased for continuous contact with the ground. In a second embodiment, the housing is fixed directly to the snowthrower body, a scraper guard plate having a bottom scraper edge is slidably attached to the rear wall of the housing, and springs connected to the housing and the scraper guard plate slidably urge the scraper guard plate such that the scraper edge is biased for continuous contact with the ground.
