I have a JD 4020 wide front tractor that just seems to have weak steering. It has a loader and 10.00 x 16 tires. I know this effects the steering but I have others setup the same way and they steer fine. Stand by pressure is at 2250 PSI. Flow is good. I have removed an rebuilt the steering valve and motor. Still no better. Spindles move easily by hand so they are not stuck. I even switched the steering valve out of one of the other JD 4020s and the same issues. So it just about has to be in the steering motor.
The steering will stall when setting still. The steering wheel moves but the tires do not. Roll the tractor a few inches and the tires will slowly steer to where you have the steering wheel turned. It acts like one does with air in the steering motor but there is not air when I bleed it. It steers like you have the front wheels deep in mud and are trying to steer it.
