Hi my name is***** will be glad to try to help. Check the screen and inside the filter for metal/debris flagginf a pump or component failure occurring. Let me know the results and if we need to dig deeper into this. We can follow up as needed.

I thought I might get some advise directly linked to the 9190, like check booster pump here or main pump for key shearing here and this is how you go about it. I already had a plan to pull screen I was hoping not to dump all the oil if I could do some other checks first. I change hyd filter a few days a go as my pressure alarm would come on for while off and on.I did not see any metal at all as I looked for it when I change filter. Tractor in field and 10 miles away, otherwise I would rip in to this.

A plugged screen will starve oil to the pump. By chance do you have the old filter? If so cut it open and check for metal PTO clutch debris in the filter paper. Squeeze the excess oil out in a vice to get a better veiw after cutting out a good size sample.

I am working on trying to figure out how to remove the pump and open the tractor up to see what is wrong

Thanks for the update. Did you find anything in the screen or filter that would flag a mechanical failure? Have you had test gauges on this to see what your pressures are in the system?
