Im sure this has been discussed a million times, but I'm trying to buy a bed edger and have several questions and I could not find what I was looking for using the search feature. We have always edged a new bed or existing bed by hand as needed. I once rented an edger that had a small 4 inch blade on it seemed to be a POS. I have also been looking at brown products. It seems that they make some nice stuff. My question is can these edgers be used to create new beds or are they really only good for touching up existing bed lines? If I am doing mainly new beds/touching up old bed lines which model is best they make so many? And is there a company that makes an edger that can completely dig out the edge and deposit the soil/grass inside the bed line or on a tarp on the lawn side. Thanks in advance for all info.
