unfortunately not out at the farm right now so can't attach pictures.
my dad made a drawbar attachment that bolts on with a 2-5/16 ball for the on-road trailers. basically a heavy steel flat bar with a couple of welded side supports to hold it straight and a hole for the ball mount. two crescent hammers installs in minutes.
if I were making one today, I would buy a 2-1/2" square receiver blank and weld up a flat hitch adapter that bolts on securely in similar manner.
then you could insert any 2-1/2" or 2" (with sleeve adapter) square drawbars. drop/raised, adjustable, fixed flat, whatever you have.
I use a bullet proof (US made) adjustable bar on the trucks and a fixed solid pintle when needed, though we don't currently have any lunette eye hitches. I'd like to have a flat drawbar to receiver adapter eventually time permitting. dad was a welder for Allis 37 years so there's no shortage of welding machines out there. I was a heavy junk mechanic so "rough" welding was in my ddr.
another popular route depending on the capacity of your lift arms is a three point hitch to square tube adapter. seems like I've seen those for sale already made but not sure of a brand. nice thing about those is readily adjustable height, just need to make sure you've got yer sway bars (stabilizers) on, especially backing.
good luck!
