PTO won't engage with motor running

It is a Ford 800, the PTO will not engage with motor running. If off PTO will engage and disengage fine. Very little end play at shaft. I adjusted the clutch, same results. I am starting to think clutch is worn out?
Also, would low gear oil be a factor?
 
800 as in what model. The 800 is a series of models and the fix can be different. 4 speed as in 840?? Or 5 speed as in 850 which does not have live PTO or 860 which has live PTO???. On the 840 or 850 the clutch could be dragging but if you have the transmission in gear then the clutch should be forced to stop and if you can sift the PTO in clutch could be dragging because of oil etc on it. If an 860 then could be the 2 stage clutch not adjusted right or the PTO clutch dragging
 
I have a 4 sp tranny and if the engine is running too fast it doesn't want to engage, nor does the tranny want to engage. Slow it down to below 900 and no problem.
