ABSTRACT:
A concrete cutting saw is provided for the cutting of grooves in the surface of wet concrete. The concrete saw generally comprises a motor driven rotating cutting blade mounted on a support structure. The concrete saw is supported during cutting by wheels, and has a skid plate with a slot through which the rotating cutting blade passes to cut the concrete. The cutting blade is mounted with a sound deadening blade housing and a number of shields and guards located about the skid plate. The skid plate is movably attached to the concrete saw and resiliently urged against the concrete during cutting so that it remains in contact with the surface of the concrete surrounding the cutting blade during cutting. The skid plate is constrained into a bowed configuration so that it is substantially flat during cutting. A variable speed transmission is drivingly connected to the wheels to propel the saw across the concrete during cutting. A sensor detects the relative position of the skid plate and the cutting blade to generate an electric signal which cooperates with the variable speed transmission to slow down the saw as it encounters hard aggregate, and to speed up the saw as it encounters soft concrete. A distance counter measures and displays the distance which the saw travels during cutting.
