2118315 9320992 PCTABS00027 A saw (10) for grooving concrete includes a base (12) supported by wheels (14, 16) such that a cutting guide may press against the green concrete with a predetermined load. A cutter frame (26) is pivotally mounted to the base (12) and includes a cutting blade (24) and drive means (28). The pivotal connection (18) between the frame and the base is spaced from the cutting blade (24). A handle (56) extends rearwardly and upwardly such that an operator may push it. The handle (56) is pivotally mounted to the saw such that pushing the handle downwardly will cause the frame (26) to pivot upwardly. The handle (56) is telescopic and may be folded. A depth stop is connected between the frame and the base to provide a depth adjustment for the cutting blade (24).
