3025E PTO overrunning clutch?

For past 3 winters I have used 64" snow blower with no issues. I just purchased a 5' Brush hog (shear pin) mower and If I (understand / read in past) it is a good idea to install a one way clutch/one-way bearing PTO adaptor? Here is the question- tractor shut off and nothing connected I cant turn PTO by hand even with pliers! I called my JD dealer and mechanic says there is no clutch in transmition and its just an electric engagement for PTO. If that is true why does any implement I have attached shut down immediately when switch is disengaged?
2nd question- I bought a PTO over run adaptor from TS, I installed it but it doesn't lock on output of PTO( it locks on PTO shaft from mower end) , it can slide off? I didn't feel comfortable running it knowing shat from mower can slide off at tractor PTO. Is that correct or am I doing something incorrect?

I like the idea of an overrun clutch. It definitely saves wear on the pto brake. You have discovered that the ones at tractor supply don’t work on modern pto’s
They are for the old ones where you drove a pin through.
I just got one for my 4720 last week after hunting around for a quick release one. I actually started a thread last year about getting one (I better update the thread).
This is the one I got:
It is good for 100hp, but they have smaller ones that are significantly cheaper.
I used it for the first time last Sunday and it worked great! The pto on the tractor stops right away, and the mower keeps turning for about 5 minutes.
Used to take about a minute to stop, and I know the pto brake was taking all that abuse to stop it.
My 64” snow blower stopped rotating in about 2 seconds, 5’ mower stops in about 2-3seconds. I don’t now how much wear on clutch, but I just don’t like it working that hard. Maybe I am over thinking it, lol

When you get the ORC on there you will be surprised by how much momentum is in something big and heavy like a rotary cutter.

You’re not overthinking it. You will certainly save some wear on the pto brake. I don’t know exactly how your machine is designed, but my 4720 has a combination clutch/brake assembly. It is wet, so it runs in oil. When the clutch engages, the brake disengages. Conversely, when the clutch disengages, the brake engages and attempts to stop the pto shaft( and whatever is attached to it). When the brake wears out, so does the clutch. Often they contaminate the hydraulic oil too as they fail. They are not fun or cheap to replace.
Whatever you can do to prolong the live is good in my book!

So I'm reading these posts to learn the best operations techniques and keep my new 3025 running without major maintenance due to operator error for as long as possible.
I've got a Titan quick hitch coming and thought that since it adds about 4" to the offset of the attachment a PTO shaft extension would also be required.
My Question is: could I use the ORC instead of the extension.

Yes you can. Most pto shafts are long enough to deal with 4 inch quick hitch , but the ORC will offset the difference.

Thanks for the information
Received my over running clutch, hope to install it and try it this weekend!

Over running clutch installed and working well. Brush hog stops rotating (at idle) after about 5-8 seconds after disengaging
