Help please

I have a 3140 John deer and lift arms will not go down will raise but won’t lower but will leak down when tractor is off and I have tried everything y’all have suggested short of taking it completely apart any new ideas?

Yes was the first thing I checked nothing happened. What happens if you unscrew it all the way out? The draft control lever is somewhat froze up and I had to use a crowbar to move it up so I could hook the lever back up do you think this might have something to do with the problem?

Is 3pt control lever rearward & your unable to move forward? If so sounds as if cam follower(shaded part)is broken or out of correct location in 3pt control linkage.
