ABSTRACT:
A snow removing machine has an auger for plowing and collecting snow, a rotatable blower for throwing snow collected by the auger, and a shooter for guiding the snow thrown by the blower so that the snow reaches a selected point. The blower has a central shaft part and blades extending radially outwardly from the shaft part. Each of the blades has one pair of laterally spaced guide walls projecting from a distal end portion thereof in a direction of rotation of the blower. The pair of guide walls for each of the blades extend divergently from each other towards a distal end of the blade.
