sorry about that, I got caught in the middle of thought and had to cut it short. What we did on a one row I-H was build the 3rd point hitch with clamps for the tool bar.That way we just mounted diff tools on separate tool bars with simple pipe stands to hold them upright when unhitched.It acts like a quick hitch, you drive away from one setup and back into the next with only installing the clamps. No more manhandling tools or needing a tape measure to put shanks or sweeps back in the right spaceing. It is much easier to slide a tool bar into a heavy tool than it is to slide a heavy tool onto a tool bar. Second thought was his welds look to be profesional so don't think I was badmouthing his work, but, without heat treating the bar after welding the weakest point on the bar is just outside the weld. If you were to hook a rock or some other immoveable object you could end up with a bent or broken bar. Then it's back to the drawing board. We had everthing from plow to planters to cultivators set up like this and could change tools in under 10 min.
