I worked for 25 years in the engineering experimental lab of a hydraulics company. Every so often in our test machines we would get a leaking heat exchanger. It's darn near impossible to boil all the water out... we would take the lid off the reservoir and heat the oil with the reservoir heaters to about 250 degrees, run the circulating pump (pump for heat exchanger and filters) and it would take days to boil the water out. Sometimes we did not have the luxury of taking that long, so the best bet for us was to drain EVERYTHING, all hoses, pumps, reservoir and put in fresh oil. I realize you can not hope to drain everything in a tractor like that, so I'd drain what I could, external lines, filter, etc., put in fresh and go with it.
Problem with water in the oil is it's like any other contaminant, especially under high temperature and high pressure... it will erode components. A pump with 4-5000 psi and water will erode just like if you threw sand in it.
