I've got a 61 Farmall 560 gas that I'm having hydraulic trouble with. I get a pulsating whine when the hydraulics are not engaged. if I engage the three-point hitch or any of the bucket hydraulics, the whine largely goes away. Engaging the PTO does not make the whine go away. in addition to the whine, the hydraulics are slightly jerky when lifting. Nice and smooth and lowering. Power seems to be reduced about 25% based on lifting capacity.
I changed out the fluid back in the fall, and replaced the filter. I checked that and the filter is clean. I pulled the screen on the pressure relief valve, and the screen was collapsed, but not clogged. Got the screen opened back up, still having the same issue.
I have not yet tried changing the pump, because the pump was new right before I bought the tractor a year and a half ago and it has minimal hours on it.
Hoping somebody can point me in the right direction
