lb1914 hydraulics

anyone got an idea why none of the hydraulics are working on this Tractor. Thanks

If the 3pt and the loader are not working then it's probably a bad pump. That being the case, you will have to find out what caused it. It could be anything from a QD not being seated properly or simply a defective pump. It's best to find out why now before replacing a pump and having it fail again.

If something is working then it's probably a loose connector somewhere.

Thanks MadReferee for your response. The 3 point will raise without equipment on but only at higher RPM. With the Tractor running i pulled the plug out of the pump and not much oil was moving. I can hear the pump running. Do you think ineed to pull the pump and see what is happing Thanks agman

Have you checked the filter to see if it's clogged? Is there a screen in the line somewhere in the line from the tank to the pump that may be blocked. Sounds like the pump is pumping but not getting sufficient fluid from the tank.

The filter is clear. The big return line seems to holding fluid in it. Maybe i should take the return lie off and ck for blockage. I red in another thread that there is a possibility that there is a ck vale in the loader joystick that if the loader was overloaded it could have something under the valve. Sounds like a long shot to me but anything could be possible. Whats your thoughts.

If the check valve is stuck open you would probably hear a high pitched whine as the fluid bypasses. I don't think this is your problem. Do you have a workshop service manual for that tractor? If not you should get one. There is not much more I can suggest at this time.
