9" Three-Point Edging Blade - Triangular 3-point blade offers versatile cutting power. Don't settle for flimsy blades that may require multiple passes, or a string edger that may never cut through to the roots! Adjustable Edging Depth - Depth control is right at your fingertips, with fixed positions from .5" down to 3". In areas that haven't been edged before, start high and make a second pass at a deeper setting to cut into roots and minimize regrowth Pivoting Blade Assembly - You can adjust the blade housing fifteen degrees in either direction, or keep it vertical, depending on the style of edge you prefer. Many pros opt for vertical edges along walks and drives, with angled cuts around flower beds or other areas where a less severe look is desired. 4 Wheels for Maximum Stability - Many wheeled edgers have only 3 wheels which can often create a wobbly ride...and that can show up in a wobbly edge. Handheld edgers are even worse. Professionals insist on 4 wheels for maximum stability. Powerful DR Engine - With Overhead Valve and plenty of power (196cc), our DR engine has plenty of muscle for cutting edges, even in tough clay soil.
