Just buy the one tractor supply sales. And throw away the "hook". Get two pieces of 1/2 steel, about 6 in x 2 1/4, and drill 1/2 holes at each end. The hook is never right. I started refabricating all my implements to fit the hook but eventually quit. Now I back into it and hook up the left and right, then get off and use the flat adapters. Every implement then works. The JD is no better. It's about the "rating". There are some cheap one's out there. The TS one does require adapters, which are not cheap. If you can find a high enough rated quick hitch without needing adapters, that's the way to go.
Been thinking about this....... if I had it to do over.... no adapters. I would take it straight to the welding shop and have them build it up, fill in to fit a standard pin, with no adapter......... hmmmm, then it may not lock in. It will need to be built upward a little. Take a standard pin to use as a guide fabricating
