Abstract: The present pull-type snow blower attachment comprises a housing, a auger and a snow blowing fan arrangement. The housing defines a longitudinally curved surface between two walls. A hitch protrudes away from the surface and is adapted for attachment behind a vehicle. The auger is rotatably secured to the walls of the housing. The auger defines two opposite sections and a middle section therebetween. Each opposite section is equipped with a spiral blade angled towards the middle section, and the middle section is equipped with at least two blades for lifting snow. The snow blowing fan arrangement includes a fan and a chute section above the fan. The fan is between the auger and the hitch. The fan is adapted for receiving snow lifted by the at least two blades of the auger and pushing the snow through the chute section.

Abstract: A snow blower comprises a frame, an auger, a fan, a hydraulic system, a rotating drum, a securing mechanism and a disengagement mechanism. The auger is rotationally mounted to the frame, and is adapted for collecting snow. The fan is mounted upon the frame, behind the auger, and evacuates the collected snow in the rotating drum. The hydraulic system rotates the rotating drum with respect to the frame. The rotating drum defines a pair of teeth about a circumference thereof. The securing mechanism is affixed to the frame, and includes on one extremity a pair of complementary circular cams, and on a second extremity a pressure mechanism for applying pressure on the pair of complementary circular cams to keep the pair of complementary circular cams engaged.
