planman,
Hello. I have a Flexpoint hitch and use it on my 2520 now and previously on my JD755 with no problems. Before I try to answer your question I will have to ask one. Are you looking to just use it to tow/move trailer(s)?
If you just need it to tow or move trailers there are much cheaper options. Bill Reugg Manufacturing makes a 3PT drawbar for towing. He has CAT0 for sure and I think a CAT1 too. $88 with shipping includes everthing except The Ball(s). For about the same money you could also get the parts to make one of these at Tractor Supply Co. You might also be able to just mount a ball on your tractor's included drawbar if you only need 1 ball size.
When bought my Flexpoint it was (I think) $199 plus maybe $35 shipping. At that time it didn't include 3PT pins which I bought at Tractor Supply where I also bought a Tri-ball hitch (another $50). Between my place and my inlaw's farm we have 5 different trailers and need all 3 ball sizes. I also got the optional weight bracket and use it for ballasting, but I already had suitcase weights.
So as to whether it will fit your 2320, I measured 25 3/8" as the 3PT width needed for the Flexpoint. So you need to set the inside-to-inside space on your 3PT arms to 25 3/8"
and if you still have some clearance on your tires it will fit. I really like mine. Its a well made product, but as I said, you might be able to find something else cheaper if you just need to tow a trailer.
