Wide surface
Style: Lawn Edger/Tool Only
The edger has a very strong motor cuts great! As long as you are placing the edger on a wide flat surface. If the area you want to edge is along the curb and narrow the edger is to big and bluky for a narrow edge strip

Very good lawn edger
It does a great job and easy to create straight, clean lines. Does not do well going around curves.
