Ford 4000 PTO

[4 horses]

My PTO over the years has worked great. End of season last year it did not engaged. Weather got cold
and it started working. Did not use it over winter but the few time I started the tractor it was spinning.
Getting ready for the summer and it is not working. Changed the oil, thought it might help, still nothing.
Is there anything I can try before tearing into the lid?
It is a 1974, pto always spun until hooked to an implement. When I lifted the lever it then engaged. The
resistance from the implement stopped it from spinning. My research shows this is how it is suppose to
work.

What transmission does it have? The PTO on the Select-O-Speed is different than the ones on the 8 speed manual transmission.

It is an 8 speed manual.

when you say started working,, did you have a load on it, or did you observe the pto shaft spinning during cold weather when the oil is thicker??

Poly tube from pump to control valve split.

no load on it over the winter. Just ad the box blade on for traction. The thought on the thicker oil is why I did an oil change.

Thanks, I will check it out.

Tried everything I could and today I lifted the lid. No poly tube, metal pick up with no obvious crack.

It was cold here mid 30 s. I started the tractor and the pto started spinning. I immediately hooked it up
to the brush hog, started it and nothing. Disconnected it and it would not spin. Today I pulled the lid and
nothing too obvious yet. I am thinking of starting with a pressure test at the control valve and depending
on what I find, move on from there. Any advice is appreciated.
