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’m guessing you bought an ORC that would be used on the output shaft if something like a Ford 8N and installed with a spring pin driven through the hole in the output shaft.
What you want is a push button release ORC. I have this one or something real similar I use on my 2025 when running heavy PTO implements.

Your pto has an internal brake I believe.

The driveshaft clutch is to protect the gears on both ends as an alternative to shear pins.

You have to stop and replace pins, when the (optional) driveshaft clutch slips you just remove the load to eliminate the slip, and let it turn without load for a minute to cool the clutches before re application of the load.

I think you are referring to a slip clutch which is different than an overrun clutch. A slip clutch will allow the tractor PTO to continue turning if the implement cannot turn (tiller hits a rock for example). The ORC allows the implement to freewheel when the tractor PTO is stopped.

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.
