Something like this??  Cat IV pins, with Cat IV drawbar too.  The tractor can run out of power before you would even start bending the thing.  Or the welds on the drawbar would go.... I dunno.  This thing was experimental, but with a little bit more engineering and money on it, it could do what you want.  Only thing to consider however is that the hitch will try to turn CW, so a major part of the load could be transferred to the top link (A-frame on the hitch would need some beefing up...).
