Hi Guys, I have a 763 bobcat and my son is a contractor so he uses it more than I do, He asked me if I could come up with a design that would dig a trench for a silt fence. My first thought would be to adapt the single plow "middle Buster" that I used with my old Ford N tractor. But I think that that may be too wide for his use. My second thought was to ask you people because somewhere, somehow, someone has probably done it before. Any Ideas for me? Thanks JIM
