A skid plate for a concrete saw is integrally cast having two end mounting portions and a middle portion with a slot in the middle portion. A horizontal slot in a leading end mounting portion cooperates and a vertical slot in the trailing end portion releasably engage pins on the saw to allow the skid plate to be easily fastened to and removed from the saw. A spring loaded latch mechanism holds the pins in the slots. A replaceable insert is press fit or otherwise held in the skid plate, with the insert replacing portions of the skid plate adjacent an up-cutting edge of the cutting blade.
