When choosing a lawn edger, consider the type and size of the area you’ll be edging. Lawn edgers fall into two main groups: electric or battery and petrol-powered. If you are mostly cutting smaller areas around gardens or driveways, the Atom electric or petrol-powered lawn edger will do the job. If you’re cutting along large curbed areas, a four-wheeled lawn edger like the Masport edger may be a better choice, because it comes equipped with a curb wheel to help guide the unit.
