Our MX5800 has the adjustable lower links and I bought the Pat's system for it. Works well. I bought the version of Pat's that fits Cat 1 implements but a Cat 2 lower lift (all of our implements are either Cat 1 or are both Cat 1 and Cat 2 compatible). I would buy a traditional quick hitch but a/ our ballast box lift pins are too far apart for the Cat 1 quick hitch and b/ some of our implements are not quick-hitch compatible, although most could be made so using a adapter.
