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?

The answer to your 1 st question ...

Implements stop Because there is a PTO BRAKE in the transmission.

This is why I use an Over Run Clutch ..So I don't Fry the pto Brake useing a Big Rotary cutter /Chipper/Blower..any implement with big flywheel mass.

You have a pic of this orc you bought or a link to what type it is??

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.

I personally don't like/utilize an ORC on tractors with live/independent pto's. When operating implement that exerts flywheel momentum I just idle engine to allow engine to cool down then turn off the ""slower turning pto"". Adding ORC could also cause pto shaft need to be shortened & adding length of ORC to tractor shaft changes the geometry of the implement pto shaft.

Looking online, I believe I am to remove grease fitting and install a locking pin into and through PTO to lock onto PTO. Then to remove it I remove both grease fittings and punch pin out. I prefer to get one that has a spring loaded locking pin (like the PTO drive shaft uses)

I'm not sure that 3025E will have a hole in the PTO shaft for the pin. The quick detach part MTB98 posted is the way to go.

 

[Ridgeracing]

I ordered the one on AMAZON, cheaper than TS as well. Thanks all for your help!

what is it that you are concerned about? what happened that raised the concern. I run pto rear and mid. If i shut down the mid pto with 72" deck, it doesnt just stop immediatley, it will keep spinning for a few seconds. Pto will NOT stop immediatley. Tha would cause a shock load. Unless i read your post wrong buddy

 

[Shortthrow50]

Also to ad, i just went down check, have 3520 cab tractor. So should be pretty much same operation as yours. with engine off and pto engaged, can indeed easily turn the pto by hand with just slight resistance. so now i see your gripe with your tractor. Must be clutch of some sort

 

[rydplrs]

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 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.

Most pto shafts have the hole.

When installing these it is important to get the pin you drive in "centered"
If not centered it will not function as desired. It will be LOCKED in place.

The other "new" type that slip on and lock with the spring pin are much more handy as it takes a couple seconds to remove or install vs 5 minutes + an hour to find all the right tools.
Mine is on and off constantly depending on what implement and if the Quick hitch thing is on or off.

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.

Yeah, with a pair of pliers I can’t even turn PTO over.

My mistake, I posted under this page and then realized I should have posted it under Implements etc.
