Hydraulic Oil Change Question

[SinkholeRoad]

I recently acquired a 560D with milky trans/hydraulic oil.
How many changes will it take to clean up?
Is there anything one can do other than drain it and change it until it clears up?

well if ya change all the oil including the PTO and let her drip dry and pull every plug you find under it . then put the new oil in along with new filters and do several more filter changes then take it out and work the snot out of it like plowing for a week or so one maybe twice but Do the filters every 15 20- hours and park it under cover as rain water can find it's way down past the shifter on them .
