I know the one mechanic in our area uses his IH Flowrater or whatever it is called to get water out of the oil. He hooks it up, runs the tractor wide open, uses it to put load on the hydraulic system, and then opens the dipstick cap slightly over the differential. The fluid gets hot enough that the water drops out of suspension and starts to collect in the bottom of the reservoir. Then he shuts the tractor off, and pulls every drain plug right away, lets it sit dry with the plugs open for a day or two (unless it is dusty or raining or something and the tractor is outside), and then puts the plugs back in and fills it up. It seemed to work on our 806. You think that is expensive for 12 gallons, now try 18; OUCH!!
If you have winters, make extra sure you get it all out, because that water can do real damage. I still don't know what to do about the crack the ice put in our 806's hydraulic filter housing about 5 years ago. To make matters worse, it sucked the cast iron chips through the MCV pump. There was a loud bang, the pressure dropped somewhat and we found metal shavings in the filter after the first change, but the pump is still operating at reduced pressure and we hope it stays that way for a while.
