I need to run 150+ ft of internet cable from house to shop. Actually its been laying on the grass since last winter and still has not been mowed in two. Before I have driven twenty miles and rented a little gas powered trenching machine to do something like this, but I am feeling lazy. Is there anyway I can do this with some kind of hand disc tool that you just roll across the ground. Only need it a few inches deep. Anybody ever trenched with a chainsaw. There is a youtube video about it.......but not sure if I want to try it.
