Live PTO/LIFT vs NO Live PTO/LIFT

Based on the explanations of LIVE PTO given so far, I would suspect that if the input of the 2nd transmission is connected to the regular PTO output,which is not LIVE, then this still would not provide live PTO. It would have to be connected to something that would not stop turning when the clutch is engaged. Sounds like this would only allow the speed of the PTO to be regulated without changing tractor speed or RPM. But I may be wrong. Robert

Not a small engineering exercise I would bet.

On rigs WITH live PTO/ hydraulics, the power for these services are taken from a second drive on the main shaft that is put into play by means of a TWO POSITION CLUTCH.

Some of the biggest tractors have the ancillary drives on an entirely different shaft with a second method of disengagement.

I hope this helps

No live PTO normally means, the PTO is run off the transmission output, thus when the clutch is pressed, it stops tractor and PTO. Unfortunately, like when bush-hogging, you press the pedal to stop, the PTO with this mass inertia of hog blades "pushes" the tractor. Many owners incorporate a "over-ride spragg" cluch at tractor PTO output, which spins and does not push tractor.
Independent PTO is still another type. The clutch has no affect on it, it can either be electric operated, or with another control, like hydraulic.
Hope this helps.
