ABSTRACT:
A self-propelled saw for cutting green or uncured concrete having a frame with rear drive wheels and adjustable front wheels is provided. The saw has a handle for guiding it along the desired path to be cut in the concrete and a drive motor for the saw blade and the rear wheels mounted on the frame. Motor or pump driven means interconnecting the handle and front wheels raise and lower the front wheels at the control of the operator to remove or insert the saw blade into the concrete to be cut. A track assembly, including a pair of parallel tracks moves with the frame as the saw blade is inserted into the concrete and the tracks engage and roll along the surface of the concrete to support the surf ace adjacent the saw blade as the concrete is being cut.
