An apparatus for cutting a decorative grooved pattern into the surface of hardened concrete, pavement or the like. The patterns are comprised of spaced concentric circles or arcuate segments or spaced linear grooves with or without selectively positioned radial or straight groove segments therebetween and variations and combinations of each. The apparatus includes either a transversely oriented frame-mounted concrete cutting means and/or a longitudinally oriented frame-mounted concrete cutting means. An arcuate tracking arrangement and a linear tracking arrangement are also provided, each connectable to the ground or concrete working surface and, at one end thereof, to the frame. The frame may be manually or drive wheel-propelled as guided by either of the tracking arrangements to produce the above-described decorative grooved patterns in the concrete surface.
