PTO on case 1959 Case 410b

[LoResSimian]

I have a general question as to how this PTO is supposed to work.
I believe the lever that connects to the piece going in close to the PTO output shaft should be engaging and disengaging the PTO.
The Knobbed handle, I think, Should be raising and lowering the 3pt arms. Not sure what the valve does that feed back to the top of the trans.

The 3pt is in an always on state. If the shaft that enters the transmission case near the PTO output shaft controls engagement ,I'll focus there first.

Thanks

Not sure what you are asking? The shift yoke engages/disengages the drive. The hand lever engages/disengages an adjustable clutch and the brake.

Thx. Joe(WA) I just want to learn how this is supposed to work so I can figure out what I need to fix or just leave as is.
Any idea what the handle with the knob does that I have pointed out in the picture? I think it raises and lowers the arms on the back. Not sure , though. I get some movement but not always. I think there is a combination of things going on there and I haven't yet guessed the correct order.
Or... there is something I am missing, (like moving the yoke with a small,prybar on the pto)
I appreciate the photo. It is very helpful. I'll see what happens when I move the yoke today.

easier yet... I should be able to engage and disengage the pto with the lever control/clutch. is that correct?

Yes the PTO clutch is engaged/disengaged with the lever. The shift yoke needs to be in the engaged position.

On the Eagle hitch, it is operated by inboard lever between the seat and the fender. The only knob I am aware of is the right draft arm leveling link. That is provided to level the arms or adjust them for whatever the implement requires i.e. when plowing one wheel is in the furrow so you adjust the arms to level the plow.

This all assuming the tractor is factory as built.

Pulling or pushing the lever is not making a difference. I can snap/pop it into and out of what feels like positive positions but it does not have an effect on the rotating shaft of the PTO.

The spring in the image is missing. Not sure what effect it has.

I try to hold the pro shaft to feel if there is something driving it and in both positions- lever up/lever down- it is being driven.

I'll have to look more at the drawing to see what is going inside.

The snap you feel is the over-center clutch engaging/disengaging. Someone may have backed off the clutch adjustment all the way to keep the clutch disengaged shaft from turning if the brake is malfuncting, the discs may be shot, There may be a gear stripped. There are other possiblitilies that will require a terdown to find. Check the clutch adjustment first.
