Does anyone have a good generic price per foot for bed edging using a power edger (Brown, etc.)? I realize soil conditions play a big factor. I am looking at heavy clay soil with moderate rocks. I am thinking in the $.15/ft. range.......is this in line with what others are charging? If anyone can provide a typical feet/minute production with a brown bed edger then I can also calculate what my pricing should be. Thanks in advance for any input.
