Abstract
A walk-behind scrubber is provided with mechanism for lowering a squeegee assembly when the scrubber is moved forwardly and for raising the squeegee assembly when the scrubber is moved rearwardly. The scrubber includes front wheels which are driven by a motor which is connected to the wheels by belts and pulleys when a moveable handle at the rear of the scrubber is pushed to move the scrubber forwardly. The motor is connected to the wheels by friction discs when the handle is pulled to move the scrubber rearwardly. When the handle is pushed, mechanism including a switch is operated to lower the squeegee assembly and when the handle is pulled, the mechanism including the switch is operated to raise the squeegee assembly.
