Abstract
A high speed vertical axis floor treating machine for polishing, brushing or scrubbing a floor includes a frame, a drive motor on the frame for rotating a floor treating element, a control handle pivoted to the frame, and a pair of ground engaging wheels mounted on an axle. The frame is resiliently supported on the axle to permit edging of the floor treating element. An adjustment rod engaging the axle raises and lowers the frame on the axle. The drive motor is mounted rearwardly of the axle to counterbalance the weight of the floor treating element about the axle.
