I'm going to weigh in with a minority report. I foolishly bought a quick hitch (the most common, heavy frame type, 2 release handles, etc.) more than 10 years ago with very naive assumptions and poor investigation before buying. Tried to use it with both the JD4700 I had then and with the MF2660 I have now. It is by far the worst, least useful, frustrating waste of tractor gadget money so far. For starters there is zero flexibility left and right in implement pin spacing. Either it fits or it doesn't. In most cases it doesn't. By the time you pull it off, stop cussing, and go back to hitching the implement directly you will have forgotten why you ever bought the QH in the first place. One could put double the good money thrown in after bad and buy both a Cat 1 and a Cat 2... I suppose. Even then many implements will fit neither one.
They get in the way (space already limited and cumbersome) for making your PTO shaft connections. You find yourself questioning whether the hitch is as reliable for many of the rough and tumble uses (like a heavy bush hog, a big flail mower,etc.). Mine sits along the wall of the shed rarely used for anything.
In my opinion the design is lousy. Zero flexibility in left right spacing is just completely unsat. I do not own the Pat's lift arm ends but they look far more practical. The extendable/adjustable ends coming from the factory these days are a big help (I do have those) and becoming more and more common.
Modifying your implements to fit the quick hitch is having the tail wag the dog all over the lot. No way would I ever do that.
If you have a few $hundred spare for goodies on the M7060 I strongly recommend an hydraulic top link. They are extremely useful for almost every implement and especially for that box grader you plan on. [Get one with plenty of length-flexibility and heavy enough to handle anything you have.] And by the way I have found it very helpful at times in hooking up troublesome implements. Things far too heavy to move by hand (say a 1460lb bush hog) can be moved around a little using the hydraulic top link, often positioning them for ease of hitching.
