ABSTRACT:
A snow thrower incorporating a device fixed relative to the auger housing around the auger shaft for generating a downward thrust on the auger shaft which opposes and balances the upward thrust caused on the auger shaft by the cooperation of the auger with the snow. The downward thrust is provided by shaping a portion of the housing for the drive of the auger shaft in such a way so as to create a static downward thrust.
