The reason I ask, is because I have a power angle plow that I use on my skidsteer. ( Cat 246 ) The fluid is used to angle the blade left and right. I'm putting a 3rd function on my tractor and the blade could be used on that as well. At this point there is some fluid in the Pistons and lines of the plow from previous use on the skid. Obviously it will end up in the tractors system if hooked up and visa versa.
