A lot depends on which tractor it maybe. I have Olivers and you can engage the PTO slowly. I have a friend who has a Ford 4600 and you can not engage it slowly it is either on or off. The Farmalls I have had with independent PTO you could also slowly engage the PTO on
New tractors have electronically controlled PTO switch. Its "kind of" gradual, but you have no control over it. The guy below talking about frozen feed wagons has a good point- You need to feather it in, to see if its froze up- with the new electronic ones, not sure if it would just kick in and bust something. Seems like they would have that worked out, as it would be a common problem in farm country.
Old tractors like my IHC 300 the hand lever controls the pto clutch directly, so yes you feather the clutch easily, simpler pull the hand lever slowly as you would a foot pedal.
Newer tractors like my ford 7700 no, the hand lever activated a hydraulic control that slams the pto clutch together, there is no way to change the feathering of that.
Some are designed to feather a bit, some of the newest tractors have electrical systems that are supposed to feather the clutch gradually. But you have no control over this.

That is exactly what happens. My cousins have a problem with their manure spreader in the winter and a friend of mine has sheared off shear pins on a feed wagon for that reason. Kind of wonder why they build them that way. You would have thought if it was electronic they would have been able to put a dial for variable speed for start up.

That was a big selling point of the 55 series hydraulic PTO's over the competition at the time. The Oliver PTO engaged gradually.
1960's John Deere 2020's with two stage clutches had mechanical linkages to both the transmission clutch and to the PTO clutch. You could feather the PTO almost as easily as the drive wheels, but the travel was shorter. It worked fine on a hay baler or a hammer mill. I think Deere called it "continuous running PTO" because the PTO could stay running when the motion of the tractor was stopped. I suspect two stage clutch on your MF50 could be similar.
I think only the 2020's with fully independent PTO had a hydraulically actuated PTO. I never drove one with a fully independent PTO so I can't say how easily it could be feathered. The hydraulically actuated PTO on bigger Deere tractors like 4230 could be feathered to start up a hammer mill.

It doesn't seem to matter how slowly I move the lever on the 4020 - it slams into gear. The 4440 seems to be more gradual but that may be because I am in the cab and cannot hear it clunking when it takes off. Either way I engage everything at an idle.
For years our mixer grinder was run by a Farmall H. When the H died we had to start using the 966. It would feather somewhat but it was hair trigger, I tell you. I can't tell you the number of shear pins we went through on all of the equipment after the H went to the junk man. That's one reason why I use my Farmall M on my grinder. It isn't like I need live pto to grind anyway.

This is my concern. My baler, hay rake and sickle mower are all at or near 50 years old. When they get replaced, it will probably be with stuff that' soundly 30 years old - LOl!!!
It's nice with the MF50 to ease these old machines into action - especially after a plug of hay jams everything up.
Sometimes when I'm bush hogging, I'm backing into some tough stuff and the ability to feather the bush hog on/off to see what I'm getting into is nice too.
Thanks,
Bill

The 4-5000 series Fords can be quite difficult to feather. The newer ones are quite easy. On the older ones I find that if you control the lever carefully and hold it near the point where it snaps in... and just ease it forward instead... you can usually feather it fairly effectively. The other alternative is to cycle it on/off a few times before easing it ahead. Later models, particularly of the 10 series variety are easily feathered. Just move the lever up half way or so and wait until it starts to power up, then move it ahead. Those are very smooth.
Electronic controlled PTO's... I usually find feather pretty well on their own. If they don't I cycle them on/off quickly until they pick up and go..

My current Branson has both a Live or an Independent clutch. Have a switch whereby I can select which I want to use. If I need to feather I use the Live. If not the Independent. The parts breakdown shows roughly a half dozen plates and discs in the independent so upon engaging it obviously takes time for all of them to connect. I don't know if you could move the in out switch back and forth and get a feathering function out of it or not.
On a clunk, I always put the tractor in idle prior to engaging the independent to reduce the stress on the whole system. Usually it is a comfortable engagement. Also at that speed, if I am engaging an implement with a lot of mass to be rotated, aka the hardest load on the PTO in starting, it lugs the engine for a couple of seconds which helps to soften the impact.

unless you have something different from any of the ones I have looked at the only thing that changes when you select independent or live is one way the pto stays on the other it shuts off when you push the clutch in. when you push the clutch in the pto switch is wired to the clutch safety switch and the pto stops. both ways when the pto is turned on it activates a solenoid which lets hydraulic pressure to the pto clutch pack. how hard it engages it determined by how fast the pressure gets to the plates.

I really was curious as to how it works with both systems, but didn't dig into it to find out in detail. Actually I never have used the live as I have a Ford 3000 with live and open station and when doing post holes, I use it or for anything else that needs feathering.
I haven't looked at the drive line up front IPB to see if it has a 2 stage clutch or not. I just recall seeing all the discs and plates for the IND and assumed that the slower the shaft was turning when it encountered something like a rotary mower shaft at rest, the lower would be the engagement stresses. Just didn't make sense to engage with the engine revved up.
