ABSTRACT:
A floor buffing machine having a pair of coaxial floor-engaging wheels for movement of the machine over the floor to be buffed, a motor drive, and a floor buffing pad support structure mounted to one side of the wheels, the machine pivoting around the wheel axis to position the buffing pad in contact with the floor, and wherein the pad supporting means provides automatic self-adjustment of the pad into parallelism with the floor as the thickness of the pad changes with wear, thus maintaining full surface pad contact with the floor and obtaining a prolonged pad life.
