I made a "turnover ball" this evening for the pallet forks using 1/2" plate and some 2" and 2-5/16" balls I've been tripping over for years (don't know where I got them). Last year I cut an 1-3/8" hole in one of the pallet fork tines so that I could mount ball hitches that have a threaded shank and nut, but it's annoying to change them out when I'm moving trailers with different sized couplers.
The hardest part of the job was cutting and attempting to drill the 1-3/8" round bar that I took off a very old JD coulter. It's as hard as anything I've ever encountered so I gave up on the idea of drilling a hole for a spring loaded clip, and welded on a low-profile loop instead. I added a link from a piece of old chain to the front of the hitch so that I have a place to connect safety chains.
I'll test it out tomorrow when I move a couple of trailers around, but it certainly fits on the tine, the pin drops in and all is good. It takes all of 10 seconds to switch from the 2" ball to the 2-5/16" ball or vice versa.
