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.

Skid plate for concrete saw

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.

A concrete cutting saw has wheels and a rotating cutting blade that cuts a groove in the concrete surface. A support is mounted to the saw to support the concrete surface adjacent the cutting blade to reduce raveling. One or more nozzles are mounted to the saw and in fluid communication with a gas source to provide a gas stream directed toward the support so the gas stream from the nozzle impinges on a leading end of the support. The one or more nozzles are located adjacent to and in front of a leading end of the support, and preferably blow on opposing sides of the plane containing the cutting blade.

Method and apparatus for cleaning concrete during cutting

A concrete saw has a rotating cutting blade that rotates in a first plane to cut a groove in a concrete surface. The blade is guided along that groove by two guides. A rolling or sliding support member on opposing sides of each guide roll or side along the concrete to support the saw blade on the concrete and to position the blade relative to the concrete. The guides and rollers are advantageously on opposing sides of the blade. The guide can be a sliding member but is preferably a rolling disc sandwiched between two rolling supports. A diverter can prevent debris from the blade from getting under the movable support.
