Need some advice We have JD model 50 with all of the bells and whistles. Have been using it for 600 hours since restoring. Hydraulics, have always worked. Running the rocker arm hitch and remote cylinder and loader. Notice last fall rocker arm would slowly drop down. Put on the JD 45 loader to feed some bales. I lifted the first bail it was moved to bunk an bucket tripped. Went back for second bale and it would not lift it. Backed off and lifted bucket and when lever released it dropped . Seemed like the hydraulic just bleed pressure off . ANY IDEAS?????. Suspect O ring seal on rocker shaft cylinder or one of check valves in valve is leaking. Have drained oil flushed and refilled. Do not really want to tear into lift cylinder. HELP
