I did some more testing today and found out the if I have the three point lever in the raised position and it will not go up ,it will when I raise the loader.
It seams to me like ther is a stuck valve somewere.Any help will be apprecaited

I am no expert but it sounds like a loader valve problem. A broken spring or stuck spool so you don't get any Power Beyond pressure to the 3ph.

Put this in the Hydraulics Section. There are a lot of knowledgeable people there who can help you.

If you have the loader hydraulic block under the right foot rest, like on my L3010, you could disconnect the pressure hoses to the loader and plug the ports then turn the block valve to the 'no loader' position and check your 3ph operation. See your tractor and loader manuals for loader hydraulics hookup to understand this block and valve.

Hello Jeremy...
The problem will be in the loader control... to confirm this, look on the right side of your tractor ...
just in front of the hydraulic filter there are 2 hoses... between those 2 hoses is a large slotted screw head... that is the selector for your hydraulic flow... Vertical is with a loader, Horizontal is for No Loader.
You can only turn it 90 degrees... turn it to the Horizontal position and check your 3point...
Put it back in the Vertical position and the hydraulic system runs first to the loader and then to the rear of the tractor...
If the 3pt still will not function, check your Loader Control linkage ... if the linkage is okay and centered... then as Gordon Gould said your problem will be inside the Control Valve... Post back with what you find.. KennyV
