A rotating pad support structure for a floor buffing machine adapted to secure and mount in contact with a floor to be buffed and to rotationally drive a flexible circular floor buffing pad. The structure comprises a drive disc which is normally supported and driven in a horizontal plane and the buffing pad is mounted on the underside of the disc so as to present the bottom working face of the pad to the floor. The disc is specially structured to provide an effective floor buffing area of the pad confined to a peripheral annulus not exceeding about 40% of the area of the pad face.
