Greenworks ED40L00 Edger, 8" (Tool Only), Green

So much better than the Ryobi one I was using. Works with 40v trimmers and pole saw I already have. Feels well built and does the same job in half the time as my old Ryobi one. I can use the same 4ah battery in the blower afterwards. Happy I got it, probably could be cheaper...

if you use a sidewalk edger this one has no edge guide. The blade continually bounces and sparks off the concrete. Give it one thing plenty of power.
