I prefer a single bar type hookup, we just use a drawbar and don't put a ball on it.I built my farm wagon from brand new Horst running gear. It's their ten ton model. You can just barely see the hitch on the end of the farm wagon tongue. So - I show you the hitch on the end of my pickup. It's exactly like the hitch on the farm wagon.
I considered a ball hitch but decided on what you see. Dragging my farm wagon around my property means a whole lot of - up/down and twisting. The hitch I have works a whole lot better in my situation. I pull the wagon with the straight pull drawbar on my tractor.

There are lots of rocks there they just are not very noticeable in that picture and the disk is helping to push some back down. Also the chisel plows don't bring up as many as mouldboard plows do, which is a major reason we went with them.That setup is putting a nice finish on your land Lou. I can get the same effect, more or less, with my LPGS and scarifers down.
The other thing that becomes immediately noticeable - Where are your rocks???
100% agree on drawbar pin slop being very necessary.
