Hello, I need some guidance on my JD 4100 hydro  The 3 point hitch will raise but it will not go down. I have replaced the fluids changed the filters with not results. I have also removed the rockshaft control value and didn't see anything on visual inspection ,but I did not take it apart. The 3 point did come down on its own when the  fluid was removed and I could raise/lower it by hand with ease. I have opened and closed the control value with no change and even tried adjusting the control value.  I am open to any help PLEASE !! Thanks.

Does it have hydraulic down pressure? Or does it lower by gravity? I'm not real familiar with those particular machines. If it has down pressure, you could have a hose collapsed that only collapses when the fluid goes a certain direction. Causing your issue.
