ABSTRACT:
A concrete grooving apparatus small and light enough to be manually propelled by an operator cuts decorative grooved patterns into a pavement surface. The apparatus includes a linear tracking mechanism guiding a cutter along a plurality of lines intersecting at a variety of preselected angles, and thus allows an operator to cut herringbone, diamond, and other polygonal patterns. The apparatus also includes an arcuate tracking mechanism for cutting a groove with a radius of curvature smaller than the length of the cart used to carry the cutting wheel. An out-of-round contour-following wheel is used in combination with a cutting wheel having a V-shaped or semi-circular profile to engrave an undulating groove into a paved surface, which produces a wavy-edged or cobblestone-like pattern.
