I'm looking into purchasing the brown bedEdger and had a question. Some of my lawns have the decorative red rock in their beds and are in desparate need of edging. My question is what kind of control do I have over the dirt that is thrown up into the bed? What I would like to do is rake the rock back about 8 inches, then cut the edge on the beds and then rake the rock back down. Does that seam feasible? thanks for your time and opinions.
