I'm bidding a job right now, and the home owner wants steel landscpe edging. She is totally sold on it. The company that I'm bidding against told them that they are the only company in the area that has the machine to put it in. I've never used steel edging before. My suppliers that I've talked to have never heard of a machine to install it, other than a regular bed edger. Has anyone ever used the steel edging, and if so, have you used a machine???
