1. A floor care machine, comprising:
a chassis having a front and a back and with a lower surface, a front surface adjacent the front, an upper surface, a rear surface adjacent the back, a left surface and a right surface; a first wheel operably interconnected to the lower surface adjacent to the left surface and located closer to the rear surface than the front surface; a second wheel operably interconnected to the lower surface adjacent the right surface and located closer to the rear surface than the front surface; a platform located substantially between at least a portion of the right surface, at least a portion of the left surface and extending rearwardly from a portion of the rear surface, the platform also substantially located within the chassis and positioned substantially directly above an axis extending between the center of the first wheel and the center of the second wheel and wherein the platform includes a top surface which is adapted to receive the feet of an operator, a throttle and an operator presence device operatively connected to and which selectively interrupts operation of the throttle; a powered wheel operably connected adjacent the lower surface of the chassis; a steering mechanism substantially housed within the chassis and having a portion that is accessible by an operator; a motor associated with at least one of the chassis and a housing, the motor having a rotating shaft interconnected to a driver hub, the driver hub having a first outer surface; a floor care element interconnected to the motor, the floor care element comprised of a pad carrier having a pad on one side and a pad driver on an opposite side, the pad driver having an opening defined by a second surface that is complementary to the first surface of the driver hub; and wherein the pad driver employs a plurality of openings that receive corresponding arms of the driver hub, the pad driver engaging a portion of the arms when the floor care element is rotated relative to the driver hub. |
