LOL! Yes

We also purchased one of these walk behind 10 years ago [Link: ditchwitch.com] and it has worked really well. We had to upgrade for a large project but the little guy did a great job. We have a lot of mature trees so the one you referenced probably wouldn't get through any roots or obstructions. Notice he is working in a completely open field LOL! I do like the concept but we will typically lay conduit vs. only laying DB wire. Definitely much faster than our solution leaves much less of a trench opening. How deep does it go???
