The Select O Speeds in about 1958 or 9 had IPTO.
The first crash box IPTO was on the 1965 4000 and 5000 models.

First truly Independent on a Ford I know of was on the SOS tractors.
They had Live PTO on some of the hundred series with the 5 speed. (x60 not x50)
Not independent, but with a two stage clutch so you could stop movement without stopping the PTO.

There was a hydraulic pto on some Jubilees

(quoted from post at 21:12:23 02/26/14) There was a hydraulic pto on some Jubilees

Do you know who made that? I'd like to find one for my Jube.
I've seen the Sherman Live PTO add on for the Jubilee.
I think essentially it was a second clutch in the drive train.
Stopped the wheels but not the PTO.

We had a customer that had one. It drove off of the tach drive. Don't know much more than that. Maybe someone else will chime in.

It was an option on the jubilee.

I have read that a Naa or Jubilee had one, but I have never seen one.

Bingo.

The S-O-S models were the first Ford tractors with independent PTO.

Independent PTO is not the same as live PTO, which was available on the x60 models in late 1954 and as a traction clutch option similar to the AC WD on the NAA in late 1952.

He is speaking of the Dearborn "Live PTO" (traction clutch) option available on the NAA model.

The hydraulic pump was driven by the tach drive.

Nearly all of these systems are long since non functional and parts are made of unobtanium.

IPTO means Independent PTO, which means it is Independent of the clutch, which means the clutch has NO bearing on the pto.
Live pto IS dependent on the clutch as was the live option on the late 8Ns and Jubilees. If you stepped on the clutch pedal Everything behind the clutch stopped.

This is a photo of the twin transmission input shafts on a Ford 4400 with IPTO or with Live pto.
The outer splined shaft runs the pto while the inner shaft runs the tranny/rear wheels.

This is a photo of the pressure plate on a IPTO tractor.
Notice the splined hub which runs the pto input shaft is riveted to the pressure plate.
Any time the engine is running - clutch in, or out
the pto input shaft is turning.

Any of the S-O-S models in 1959 from the 01 series tractors.

NO 8N I have ever heard of had the IPTO and the jubilees that did where some sort of after market rig that did some sort of hyd thing. If one wants a good one get a Oliver and have something good

That system used a wet clutch in place of the sliding collar to engage the PTO... but it remained transmission dependant... so I'd not refer to it as an IPTO.
You could engage or disengage the PTO at will... as long as the transmission was turning... but if you disengaged the dry clutch everything still stopped.

The Jubes never had IPTO.
Some of them did have a form of Live pto.
