Assessing water in hydraulic oil

[William1]

My un-expert feeling is... run an acceptable, cheap oil. Half a hour, working all components of the machine. Drain, refill and then run the tractor hard (six hours of work) to get it real hot. Water will 'boil off'. Every hour during this hard day, check the level, it should drop if there is still water in it. At the end of the day, drain and do it one more time.
I'd not run-flush it with anything but acceptable hydraulic fluid.
To those that might know, can a 'Mr. Funnel' be used to trap the water during a flush?

First verify the at full capacity. Do a 100% drain and determine how much is left in cylinders etc. Fill with diesel fuel, run all hydraulics 1/2 hour and drain. Repeat with second fill 50-50 diesel and hydr oil. Then conplete by filling 100% hydraulic oil. Let the 50-50 mixture settle and any water in on the bottom.

That would be a great way to destroy a lot of the tractors systems!
Running diesel through the hydraulic system is an extremely BAD idea period!

Diesel in a HST would instantly destroy everything in it.

You put diesel in your hydraulic system and "....run all hydraulics 1/2 hour and drain". Then report how your HST operates!!! Advice no one should follow.

Late to the show, but man.......
