A quick change mounting system for grinding and other surface preparation pads provides a simple and effective way for the pads to be mounted and changed on the mounting plate of a large surface preparation machine without removing the mounting plate from the machine. (This method also allows that existing mounting plates and preparation pads may be used with a minimal amount of adaptation.) The new quick-change system makes use of a unique slot design (using countersunk keyhole slots) for mounting the pads on the plate. Studs fixed on the pads fit into slots on the plate and may lock into position. In operation, centrifugal and other forces then help to further seat the pad onto the plate.
