SMTA IPTO

Sorry to ask again but I believe one of my questions got loss in the other thread. Can you turn the PTO on and off at will using the lever without using the foot clutch or stopping the tractor. In other words can you turn the PTO on while driving down the road?? Thanks
 
IPTO stands for "independent power take-off". They are also called "live power take-off". The input side of the IPTO always rotates when the engine is turning. The output side is controlled by the PTO lever. The SMTA IPTO is the single most important feature of that tractor. The TA (power shifting) comes next. The IPTO elevates the SMTA into the realm of modern tractors.
 
that was the whole idea behind live pto. to be able to start and stop without using clutch. example is baling hay.
 
I was heading out the door to put a wiring harness on the Loboy when I answered your post. Too cold out there after yesterday so back in with more time. Let me elaborate. Wardner gave you a great answer, here is how it works in application. I cut and bale hay with an SMTA. There is a mile of road between home and hayfield. Years ago I trimmed all the branches so I could drive on the road edge and not catch my cutter bar. I have a midmount mower and I routinely activate the PTO on the way down to lop off the green shoots that stick out every summer. I also shut the mower on and off in the field if I have to and same with the baler if moving from place to place. All without hitting the clutch.

The flip side of that coin is when I am baling and see the baler getting overloaded. I can hit the clutch and take her out of gear and the PTO continues to operate until the baler is clear. Then I put her back in gear and continue. The PTO never stops. Get it? HTH
 
Got it. When I was a kid I baled a lot with a WD & WD45 Allis with the Roto Baler. Here you used the hand clutch to stop the tractor while the bale wrapped. With the SMTA you would use the foot clutch. Thanks
 
this is also a good example where the T.A.is handy to get through a thick spot. you can slow down the tractor speed and keep the same PTO speed.
 
I sure don't know how you reached that conclusion.This is a great forum and I have never witnessed a single occasion where I thought anyone was anything but honest. I simply didn't see where anyone had answered my second question which dealt with if you could engage on the run. Perhaps I missed it.Sorry if I left thr wrong impression
 
"What, you thought we were lying in the other thread?!? "


Rude and unnecessary. He explained his reason for asking.

(quoted from post at 10:05:15 01/02/11) So are you saying you do not have to stop the tractor with the foot clutch in order to engage or disengage the PTO? You just push the lever one way or the other?
Thanks

That's what I'm saying. I don't know that ALL SMTAs had independent PTO, but it was first available on that model.

Here's the other thread if you lost it...

I have to agree the IPTO is a more important addition than the TA, but both are really handy additions. Dad bought his first JD 60 in '53 and the IPTO or LPTO was great. You also didn't have to worrry about your PTO load "pushing the tractor" when you stopped the ground speed with the regular clutch, as with a rotary mower or baler.
