A front pair of drive wheels, rear pair of drive wheels, and a storage surface/wheels can be connected to the housing. The housing can be configured to be placed upon a ground surface in two different positions: a use position in which the front pair of drive wheels and the rear pair of drive wheels contact the ground surface; and, a storage position in which the rear pair of drive wheels and the storage surface/wheel(s) contact the ground surface. A handle can be provided that is moveable between a use position, storage position, and an intermediate position in which the machine can be pulled/pushed around into and out of storage by the handle.
