Abstract
A snowblower with a propeller drum seated on a free support axle that is disposed horizontally and perpendicular to the driving direction. The support axle is operated by a drive which is situated centrally within the drum. The snowblower also serves a lateral snowblowing function by the connection of a snowplow in place of the usual second drum. The side of the snowplow adjacent to the propeller drum is fixed rigidly to the housing. The back side of the snowplow is connected to a bushing which can be placed on the support axle normally provided for the removed propeller drum.
