I tried to get a Horrible Frieght quick hitch to work with my old 790 and a few implements I had at the time. After lots of modifications....I gave up on the quick Horrible Freight style quick hitch and put on the PATS. Now I have too many implements to consider going to a I-Match style hitch (I wish it would have worked out....but alas).
The PATS quick hitch brackets are the deal for me - more versatile with various implements. Fast enough for my needs.
