Tomcat's 20-inch pad driver holds a floor pad or pad-driven attachment onto a rotary floor machine, using a 7-lobe lug pattern (orange) to clip onto compatible machine drive blocks. It provides a secure, quick-change connection between the pad and the machine so pads can be swapped without tools. Confirm your machine's lug pattern matches 7-lobe orange before ordering, as specific machine compatibility is not listed in current product data.
