John Deere 650j hydraulic lift issue
Okay so here’s my issue. JD 650j hydraulic fitting came loose during operation and drained all my oil. I replaced oil and put a new hydraulic filter on. My angle and tilt will work just fine but my lift cylinders will only move about half an inch. I tried bleeding cylinders, still no luck. Any advice is welcome!

Have you solved the issue yet? If so, what was it?
Since the other two functions work I would expect that one to as well on the manual valve. Cycle the control a few times and it should clear itself. If you have the integrated valve for auto grade control, I suppose something could be holding it out electrically. Any wiring disturbed while doing the repair?
Do you have the tech and operator's manuals for it, so you can follow the circuits and study the diagnostics and troubleshooting? Hope someone with something this modern sees this, and can be more help to you.
