I build my own machines for drops and bores. I modify snowblowers for drop between 6-8 inches. Here is a video of the machine. I have over 50 deployed and am adding more each week. We would never get the production numbers I need digging by hand. We use wompers only when necessary but it can not match a cable plow.

I also mod 25 ton log splitters for driveway and sidewalk bores.
