I have a KK subsoiler that I have been using. I think I have subsoiled about 4 acres at 14"s.
So, with the 4520, I am 71"s wide. That kind of sucks because I cannot get overly close paths without running over the center of the line I subsoiled.
So, I am thinking about making a wider chisel. The current chissel is about 2.5 inches wide. I am thinking about going to about 5 inches. It makes me wonder if I would stress the KK unit too much? I have zero issue with pulling it! I think I could pull 2, and maybe that would be the way to go.... But I would like to work with what I have for now.
