ABSTRACT:
A saw for grooving concrete includes a base supported by a plurality of wheels such that a cutting guide of the base may press against the green concrete with a predetermined load. A cutter frame is pivotally mounted to the base and includes a cutting blade and drive means mounted thereto. The pivotal connection between the frame and the base is spaced from the cutting blade such that pivoting the frame with respect to the base will raise and lower the cutting blade between operative and inoperative positions. A handle is connected to the saw and extends rearwardly and upwardly therefrom such that an operator may stand behind the saw to push it during operation. The handle is pivotally mounted to the saw such that pushing the handle downwardly will cause the frame to pivot upwardly with respect to the base. The handle is telescopic and includes a pivot connection such that it may be folded to a storage or travel position. A depth stop is connected between the frame and the base to limit the travel of the frame towards the base, and thus provide a depth adjustment for the cutting blade.
