Something went wrong after Hyd oil change.

4 or 5 minutes of operation with adequate, albeit somewhat generic, UTF would not cause this. Period. The mind boggles. Operation might be sluggish or weird if the fluid really, really disagreed with the tractor, but not this. No way. If you replaced the same number of gallons as you withdrew, that is also not an issue.
I do still wonder about how many drain/fill points there are on that tractor. If there is only one drain and one fill, then those were the one you used.

The problem no doubts stems from the wrong filters. Upon starting up for those 4 or 5 minutes, you state your operation was wacko from the get go.

That tells me that those filters were wacko as well. The flow was unable to reach proper pressure and something either air locked, as you suspect, or was momentarily dry and seized or got hung up, internally. A valve or some such is jammed or partially so.

Finding out now, what to do, is going to take some sleuthing. Stay with the air investigation right now. That and the proper filters. Take this one step at a time.

I'm also thinking filter.

I have seen some machines that won't even build engine oil pressure if you use the wrong cartridge. I know that is not an apples to apples comparison here.. But IMHO.. the filter is making more difference in this equation than the fluid.

I put the original old filters back on and it didn't seem to help. I'll have some new ones next week, too bad they are 102 each.

Which leads me to say that while new filters is a good thing, the "hic up" has already happened. Putting the old ones back on did not fix the issue. Got that.

Air somewhere, but how to bleed it out? And where?

Or, something got jammed or stuck internally when you fired it up and it tried to pull fluid with those wrong filters. Man o' man, I hope it isn't the latter.

Get a hold of your nearest Deutz dealer and see how to bleed the hydro. I think you will be fine after that.

Found a Air Pocket up in the oil cooler and a little in the top of a Banjo fitting. Dad Bled it and said it's back to normal. Lesson learned for me.

Thanks for posting back with this good news. We don't always get to hear how things work out, good or bad.

Air. Kinda figured all along. Glad you got rid of the issue.
