I put a pair on my Yanmar of the type that you weld on above the ball, They are basically just block of steel with a U shape with the U side nearer the tractor a couple inches longer than the outside leg that you just put a pin in to hold the implement on. They semi-work OK. I have lost a couple of pins out of them when bushhogging and had the bushhog climb up the tractor tire a little before I could stop and now I just use the balls which is just a little more difficult if you get straight on your equipment. I think the Pats quick hitch would be lots better with a more secure lock, however I think if I had a new tractor like yourself, I would invest a few more bucks and see if I couldnt find a pair of telescoping links that I could totally replace the lift arms with. The Pats are over $200 and I would think for not more than double that, you could buy telescoping ball links for the lift arms. Either replace the whole arm or buy them and weld them on your existing lift arms. I know I could make a set of Kioti arms work or NH and MF also has them on their 40-50 HP models. The arms could even be slightly longer than yours and still work (I wouldnt go shorter due to wheel clearances) and at most you may have to drill in a new hole location for the lift rod connections and hopefully with some careful measuring and checking with different mfg. you can find one that will be just right so you could just unpin and repin the new one.
