John Deere Tractor Loader Sagging

Mathew	I have a J.D. 770 and the loader has suddenly started to “sag.” Every time I raise it, it immediately starts to lower the bucket. I have checked the hydraulic fluid and it appears to be okay. There is also no visible sign of leaking of any sort. I have used it for clearing some pretty heavy brush for about a half dozen summers, so perhaps something is stripped(?) Any information or suggestions will be appreciated.
Tony	I believe you have an internal leak in the lift cylinders. Replacing the internal seals should fix it.
Ron	If the unit still has lifting power, check the control valve. It may have a leak around an internal seal or gasket, or it may not be returning to the center or off position.
