We spent more than 100 hours researching and evaluating the best edgers on the market. At the end of our analysis, we chose the Southland SWLE799 as our top pick. Its 9-inch blade can slice 2.2 inches below the ground to get to your grass’s roots. It has a useful curb-hopping feature that will help you cut a straight, clean line on the outer border of your lawn. In addition, the fuel tank holds up to 54 ounces of gasoline, which is more than enough to get through a large project on a single tank.
