when my engine is off, i don't think i can spin the pto by hand in either the engaged or disengaged/braked position, only in the middle position.
4300 PTO won't disengage.

Prolly there had to be a CA option, either on or off, no neutral.
I'll get a pic of the three symbols on mine. Clearly three positions. And clearly a neutral, free spinning, which I use often to avoid the wear of braking. But braking is good when wanting to shut off quickly, and not spin down.

i haven't had a chance to actually USE my pto yet...need an extension since all of my pto shafts are too short for this tractor...but i did a test on my grandfather's brush hog.
from rear position (off/braked) to center (neutral?) the shaft had a small surge...tried to turn but couldn't. from center to forward (engaged), it starts up. when moved from forward to center, it still spins but has no power...begins to slow (like pushing clutch on a non-live pto tractor). center to rear, it stops with the brake.
i'd just assume go to center until it coasts to a stop when possible...seems it would be rough on the brake going from engaged to brake while the thing is still spinning fast.

That is why so many have failed.
All I can say is that I have the latest Tech Manual and parts PDFs from
JohnDeere, and there is nothing in either to indicate there is supposed to
be a neutral option. I operated mine many times with the top off to see
how it was supposed to operate. I still don't like it. If you can disengage
the PTO without jambing the brake on, that's a good thing. If I get the
last 4300 at the rental center, I am considering eliminating the brake
entirely. It is unnecessary and causes too many problems.
I should have taken a video when I had mine open.....
when i get mt pto extension, i will test it out further and let you know what is happening. i agree that is seems that some (most?) don't have a neutral position...since the diagrams/pics in any of the manuals don't seem to indicate it, not even in the pictures of the pto lever. but, as beenthere also states, there seems to be three definite positions of our pto levers.

mine has a different picture in the center. same one that dfkrug had in the pic he found. i will get a pic of it as soon as i remember to take the camera out there! yours seems to depict a neutral better than mine tho. i have a power reverser tranny, which do you have? if i recall, dfkrug has a hydro.
in the meantime....i did a small test. engine off: pto lever in braked/off....shaft turns maybe 90 degrees by hand. pto lever to engaged, can't turn at all. pto lever to center, shaft turns freely. i hooked one half of my mower pto shaft on to use as a crank.
when my extension gets here, i will do some testing under power.

I just went out and tried mine. 4200 HST. I bought that sticker in 2008 so I don't remember what was there before.
On, Off, and an obvious detent in the middle for free-spinning. And I mean obvious. The lever stops a little before the middle and you have to apply a little extra force to get it to go to on. On the way back to off the same thing happens.

Searching through the tech manual reveals some interesting tidbits:
4-24: voltage must be present at the following components with the key switch in the
RUN ("ON") position, transmission in NEUTRAL, PTO(s) in NEUTRAL, park brake ENGAGED, and operator NOT ON seat:
4-40: Operating Conditions (Running Tractor):
• Key switch must be in the RUN position.
• Operator ON seat
• PTO DISENGAGED
• Park brake ENGAGED
Operator can leave seat. (See "ENGINE SHUTOFF
CIRCUIT OPERATION")
• PTO can be ENGAGED
4-58: Test Conditions:
• X6 to control panel disconnected
• Key switch in RUN position, engine OFF
• PTO in NEUTRAL
4-138: Operating Conditions (Starting Tractor):
• Key switch must be in the START position.
• Operator ON seat
• PTO in NEUTRAL
• Transmission in NEUTRAL
So they clearly make a distinction between the three positions. I don't have an electronic copy of the operations manual and I don't want to do a "find" by hand.

It does say in the manual to engage the PTO at low RPMs and then ramp them up after everything is spinning. And it says to go down to low RPMs to disengage too.
