The best edger for your lawn depends on the size of your yard and the difficulty of the job. For large areas, a heavy-duty gas trimmer is ideal. For medium and small lawns, electric edgers are more affordable and still tough enough to get the job done. Battery-powered edgers don't have the horsepower of gas and electric-powered edgers, but they are quiet and convenient. They work well for small areas for well-maintained lawns that don't need heavy-duty edging. Combination tools convert from an edger to other common garden tools such as trimmers, cultivators and blowers.
