A snow removal apparatus having a housing with first and second chambers that are in communication with each other. A rear wall and a pair of end plates form the first chamber. Each end plate has a leading edge that is positioned in an offset manner by a transition member, and each transition member is configured to act in a wedge- like manner to split sections of hard packed snow from a larger mass of snow. An auger is positioned within the first chamber and configured so that it is able to move snow towards the second chamber in a controlled manner. The auger includes at least one feeder paddle that is configured to break-up and distribute compacted snow before it enters the second chamber. An impeller is positioned in the second chamber so that its blades project into a portion of the first chamber where they are able to engage snow that is extruded past the auger ends. The blades of the impeller include sidewalls, which also break-up and distribute compacted snow before it enters the second chamber. As the snow enters the second chamber, it is accelerated by the impeller, after which it flows into a rotatably mounted chute that directs the snow away from an area being cleared.
