OK now I see where I was wrong.
I was thinking a 841/8N/9N/ect with regular pto would be a ground drive because it was run off the back of the trans or output shaft.
That is wrong.

So with that info we would then have.

Regular PTO; 8N/9N/841/ect.....
This pto is run off the trans input shaft so engine rpm decides the pto speed and NOT the ground speed. Since it uses the same clutch as the trans you can not stop the tractor with the clutch with out stopping the pto.

Live PTO; 860/660/2000 ect. any with 2 stage clutch.
This pto is also run off the trans input shaft so engine speed decides pto speed and not ground speed. Since it uses a different clutch disc and input shaft from the transmission (2 stage clutch and 2 input shafts) the pto can be operated separate from the ground drive with the clutch.

Independent PTO; SOS and others.
This pto gets its power from in front of the trans clutch or straight off the crank. It has a totally separate clutch to operate the pto. This is the only set up that has a ground speed option. Since this set up does not use any trans gears or pedals (clutch) it can be operated totally independent of the transmission.
