Abstract

A floor scrubber includes a motor coupled to a drive member having at least two drive lobes. The drive member is received in a receptacle of the brush having a sector for each lobe. Each sector includes a drive zone and a release zone with a retainer member between each drive and release zone. A controller (circuitry) prevents the brush from being driven in the raised position under normal conditions to prevent accidental release of the brush. When it is desired to unload the brush, it is raised, and the operator actuates a keyswitch to energize the motor momentarily. Subsequently, when the keyswitch is released in the unload mode, the motor is abruptly stopped, permitting the drive lobes to override the retainer members, and to place the drive lobes in associated release zones, thereby releasing the brush.
