Just received my new edger last week. The machine is a real tank. Im just curious of how I can justify charging 60$ to use it when it can do about 100' per minute, I mean I can do a house in less than 5 minutes. Im thinking of offering a areation bed shaping special for 110$. Also has anyone used the stump rotor on one of these macnines? Seems it might be a worthwhile investment.
