Hello! I got your pm...
Well I am not sure what brand it was but it is a ride on trencher that I got from my local rental place for like 75$ a day (I think) They had 2 to choose from, walk behind and the one I got. The one I used cut a path 6in wide and 54in deep.. I will try to dig up the pics.
Also just to let you know, Last year I was planning on doing the same thing, I then found out what I was planning is now against code in my city, You may want to check in to this..
