3 point hitch

[Patrick553]

My three point hitch on Ford 1715 won't operate. Fluid levels are fine, front loader operates and there is hydraulic fluid to the control valve. Any ideas what else to check?

Welcome to TBN.

Does the hitch not go up?

Or does the hitch not go down?

Have you check all points connections something may have loosen also debris build up.

Neither direction, stripped it down to the KBM valve body. Can't see a thing wrong, o-rings look fine, linkage all operating, fluid to the valve. The lift cylinder seal is dry on the case side.

No leaks, recently serviced by a New Holland dealer. Fluid levels fine, front loader works so it's not a pump issue. Broke it down to the control valve, don't see a thing wrong externally

Linkage disconnected somewhere?

Nope, no fluid getting to the lift cylinder. Got to be a problem in the control valve. Bypass somewhere. Could it be air locked?

I have the same issue with 3 point trying to lift . did poster ever figure out problem ?

Do you have rear remote(s)? If so, is it in the neutral position? On some tractors the pressure feed to the 3-point goes through the rear remote valve, and if the rear remote valve is not in the center (neutral) position, no flow gets to the 3-point control valve. This is more common if your rear remote is the detent style installed with backhoes.

No remote s three point quit as soon as I changed the loader controller. All I did was removed hoses from old to new controller. Three point will raise as long as there is no weight on arms and they will stay up .
