What color?

[Willyr]

.......... Is the hydraulic oil supposed to look like? In my new holland it looked like vegetable oil. I just took the rigamaroll off the side of my tractor and found what looks to be coffe with a lot of creamer.

That color sounds like old fluid that has moisture introduced to it at some point.
Colors of hydraulic fluid will vary but the "creamer" should not be there. Time for a flushing.
My 440 had similar oil and "creamer" when I got it.

Flush the system out as described in SM2019 section 180 - 15 -13, top left corner of the of the page.
You can drain the lines going to the cylinder(s) also by disconnecting them and letting them drip out, remove and drain the cylinders also. I always fill the cylinders full of oil before attaching the hoses, pull the shaft all the way out until the piston hits the end of the cylinder, fill the downforce side of the cylinder with oil then carefully fill the lift side with oil and attach the hoses. Once you are all buttoned up start the engine and cycle the cylinders in and out with the engine idling to help work the air out of the system. I do not connect the cylinders until I have cycled the cylinders in and out several times.
