ABSTRACT:
A snow removal machine of this invention has a blower provided in a blower housing for throwing up snow collected by an auger toward a chute. The blower has a plurality of supporting members provided on a drive shaft for rotating the auger and the blower and a plurality of throwing-up blades attached to the respective supporting members. The throwing-up blades are elastically deformable. A vacant space is formed between the supporting members and the throwing-up blades. The vacant space allows deformation of the throwing-up blades in a direction opposite to the rotation direction of the blower.
