A pad drive assembly that detachably grips and rotatably drives a selected maintenance pad by a floor maintenance machine, comprises a rigid, substantially circular back support that has two faces, one of which is substantially planar. A substantially rigid pad drive or grip plate of planar, circular configuration is defined by two faces. One of the last mentioned faces is bonded to the planar face of the back support for rotation therewith. The other face of the pad drive is formed with a plurality of substantially rigid, upstanding pins that extend therefrom and that are adapted detachably to grip the selected maintenance pad and rotatively drive the same.
