The PTO is a very simple operation, sliding a collar over to lock in the PTO.
I assume you have the clutch in? No bad noises?
I’ll try to look at my spare PTO to see if the is a rod that could get rusted.

Thanks for responding, However I am a new owner of this unimog 419 And had to replace the 8 speed gear shift supporting collar already now gears shift smoothly.
But still won't go into PTO gear , shift lever is stuck foward, Is there something I'm missing, does unimog need to be in a certain gear or neutral , to engage PTO

Are you in Georgia? There was a unit being sold down there that was in rough shape and had some mechanical issues. I hope you got a good price if it wasn’t shown as running.
No specific gear is required. Clutch needs to be depressed.

I would cruise over to the local car parts place and get yourself three or four cans of your favorite penetrating oil. Just resign yourself to squirting everything that moves. Let it sit for a day or two, then come back through and do it again. There are all kinds of spray slick stuff. Pick your poison and just do it. You can buy yourself a gallon of Acetone and a gallon of Dextron and make a 50/50 mixture. Load it into a spray bottle and that will work the same magic.

MY GUESS is that the cable that engages the PTO is just rusted to the sleeve. Soak it with your chosen slick stuff. Believe me, you are not the only problem with a "big green toy" that has something seized up on it.

Evverybody else has already mentioned that the gear goes into neutral, so I don't have much to offer there. Have you by chance downloaded the student guide for that machine?

You are correct here in GA. Ok Cool must be stuck with rust. Transmission was filled with water, drained a few times refilled with gear oil. Bought this unimog at a auction in County of Swainsboro GA maintenance department about 4 months ago. The City was using it untill they parked it 5 years ago only has 1500 miles on it. Transmission now shifts thur all the gears with ease except PTO is stuck/jamed any Suggestions

Well, I would say a transmission full of water is a key clue you omitted.
