I have had since 2019 Star Kimodo lawn edger The Star Products Kamodo 152F is a 2.5 HP, 4-stroke overhead valve (OHV) lawn edger. Its possibly a clone of a nip engine maybe a Honda Eats plastic stormwater drain pipes located close to the gutter with ease. It has a special mechanism for locating concrete edges Unfortunately is not a bisexual machine you need to run it with the depth keeping wheel on the concrete so its only good for one direction.
