I just got a wd or wd-45 with a hitch and a loader on it but the hitch and loader both are stuck all the way up and wont go down. They are plumbed into an auxilary valve that u push one way and the three point goes up or down and the other way the loader goes up and down. What could cause the hydraulics to not work right, the valve looks like someone has had it apart and it doesn't act like it is working right but i haven't had time to fix it. Anyone got any other suggestions.

Check the traction boost linkage on the bottom side of the hydraulic pump. Control knob "A" should be locked down into the pump body detent. If it has worked loose (or in some cases fallen out) and the linkage to the snap coupler is not adjusted properly (or missing as in my case) the pump goes into full lift and ignores the hand control. If that doesn't work, your pump's internal control valves may be stuck in full lift. You can try and turn control knob "D" on the front of the pump all the way in. This may unstick the valves. If not, you'll have to pull the pump and disassemble it.

Good luck!

You would still have to move the hand lever up at the steering wheel to the down position. You could remove the addon selector valve and replumb the three point cylinders to their original configuration and see if they will power raise and gravity down(might have to stand on the lift arms). If they still go up and will not gravity down the valve assembly in the pump is sticking.
