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?
