In the video, you will see our laser trencher. On this project, we installed over 23,000 feet of 4" seepage drainage on a polo field. We installed them on 20 foot centers. The field is approximately 13 acres so any closer would have been cost prohibitive. The main branch was 6" seepage drain pipe. The average lateral length was around 200 feet. The trenches were dug 24" deep and 8" wide. The depth was required to handle the length and allowed for us to get under the irrigation easily.
The problem was that the field had only a 1% fall from side to side. This does not sound like much, but over the 600' width it is about 6' of fall. This sounds like a lot until you get out and see the field. When turf is added any little bird bath exacerbates the problem by holding a huge amount of water.
The trencher, as you can see picks up the spoils and ejects them into a Pronovost trailer to be hauled off. The entire system is automated and runs off lasers. After the initial setup, you can just take off and drive. It will carry any grade you desire. On this particular job, we were removing about 2.5 cubic yards every 35 feet. So on a 23,000 foot job you can only imagine. The project took us a little over 10 weeks.
Before we started the project, it was very difficult to walk on the field. When we were finished, after a 1.5" rain, we could drive on it in about a day or so.
