I last used my plow a week and a half ago. I went out to test it today(an old Meyer I bought used) and it would not move in any direction. I bled off the fluid and it was milky white. I refilled with new fluid and it is working now. I'm wondering what would make the fluid white and why would the plow not move? There is one place on one of the arms that it leaks fluid just a tiny bit, but no big puddle or anything. Does anyone have any experience with this?
