Snow removal machines are provided that have an auger assembly for directing snow rearwards to be received by a discharge chute, and an auxiliary snow moving assembly for directing snow rearwards to be received by the discharge chute. The auger assembly has auger blade(s) coupled to an auger axle for rotation therewith about a first axis defined by the auger axle. The auxiliary snow moving assembly has snow moving member(s) coupled to an auxiliary axle for rotation therewith about a second axis defined by the auxiliary axle. The auxiliary axle is lower and rearwards of the auger axle towards the discharge chute; and an auxiliary drive assembly is configured to rotationally couple the auxiliary axle to the auger axle such that rotation of the auxiliary axle is driven by rotation of the auger axle.
