changing hydraulic oil 2130jd (part 1)

I've owned my tractor for about 7 months now, and the hydraulics have gone from sluggish to inoperable in sub 0°C temperatures.
My thoughts before beginning were; worst case scenario, my pump is failing. Best case, the previous owner fell behind on maintenance and a simple oil change will solve the problem. Another possibility is water leaking into the oil from somewhere.
After changing it, it looks like scenario number 2. I'll be sure to keep an eye on it and plan on changing the oil again in the spring.
