Given that you could make it slip with great force.. I would think is moot.. as that great force is probably what the shear pin is in the system to prevent.. I.E. the shear pin pops before the ORC functions incorrectlyand bypasses during a gross load exceding its designed capabilities...
I would also agree that a quick release one is the way to go.

I guess I am belaboring the point now, but sometimes with this type of communication, it just does not get through. And sometimes, I do not tell enough of the story to make it clear.
Somewhere along the way, I bought a NH 1925 this year, after reading all the great information here, I found a reference where I should be running an over running coupler / clutch when using a bush hog to prevent back driving of my HST xmsn. (relevant post on the NH board) I asked several folks, the dealer I bought my tractor from and the NH dealer if I could just leave the ORC on when using my other PTO driven equipment and everyone said, all it would effect was driveline length and if the implement was spinning faster than the PTO.
I then bought the only type I had seen that pinned on.
So, after crawling around in the rain and in the dark installing this thing which while it sounds very straightforward and easy, caused much cussing and greif before I got it all lined up and finished off so the wife could use it the next morning.
Bush hog stuff went fine, then had to switch over and dig / drill some holes. Had been using the PHD no problem in the past.
The PHD would spin and start to dig, then it would stop, Thinking I had sheared a pin I lifted it and it started spinning again, up, down, up down, yep, you get the picture, the village idiot drilling holes. Pull the pin, (bolt actually) and look at it, scratch my head, wonder what is wrong, realize that I have added the ORC, oh it must be defective. Of course I do not have the tools with me to change it. Home we go, this job not getting done today. Get another ORC from my dealer explaining that this one is bad / defective and will not drive my PHD. Dealer agrees, sureley something must be wrong.
Install new one, test in yard, same results, then take the new one apart to see how it works, maybe it is backwards, spend an hour drawing circles in the air and looking at the rotation of my PTO trying to figure out if the darn thing is backwards or not. Go to rural King with snap ring pliers and dissasemble one of theirs and see if it is the same??? Go to TSC and do the same. Wander around on the web till I stumble in to the QD ones and realize that this is probably done becuase they do not work for driving all implements, if they did, why bother with a QD?
Go to my dealer, who thinks I am nuts and disassemble his, and another on the shelf from a different vendor, they are all the same.
Finally buy the QD one and mount it on the bush hog where I leave it because that is where I need it.
Soooooooooo, That is why I suggest buying the QD over running clutch.
And it never came close to shearing the shear bolt on the post hole digger when we were using it. And we probably shear 2 to 6 of them a day when we are using it heavy for planting.
Yep, I am bored and the wife is aggravated with me /forums/images/graemlins/smile.gif
Oh, and I do not care how things were designed to work, I just worry about what really happens.
