A second rotary member is rotatably fixed to the auger, the first and second rotary members forming a first pair of rotary members and being in selective operative engagement with each other, whereby the auger is selectively driven by the engine. An axle is connected to the frame and has a third axis of rotation, the first, second and third axes of rotation being substantially parallel. A third rotary member in is operative engagement with the axle, and a pair of ground-engaging wheels is attached to the axle. A fourth rotary member is rotatably fixed to either the auger or the engine output shaft, the third and fourth rotary members forming a second pair of rotary members and being in operative engagement with each other, whereby the axle is driven by the fourth rotary member.
