M4900 3point lift quit working

[BigRob49]

Does anybody know what could be causing the 3 point lift not to raise, the loader and everything else hydraulic is working fine. Was mowing and all of sudden mower is digging in the ground lift will not raise,took mower off still nothing, fluid was 2 gal low but nothing leaking,checked linkage on lift and draft all looks good. Any help are direction?

Sounds like a bad oring and back up rings on the piston of the 3PH.

Longshot - Do you have remotes fitted? If you do, check to see they are centered.

Check for a loose feedback linkage, it will come off of the top of the three point arms and connect back to the three point valve, or controls.

Hi Big Rob, Have you found the problem with the 3pt hitch not raising? I'm having the same problem.
