I have no problems of such on my 5410. What were they doing with the rock shaft? If it was a dealer that did the repair you might see if they'll repair it for free or at least half cost, since they caused the problem.

5210 3pt hitch hick-ups or hitches when running, but does not leak down when shut off
I have removed inspected and resealed scv, rock shaft cyl. and rock shaft valve, assembled and tested no change. Hitch does not leak down when loaded if not running, but with tractor running, supporting load it seems to leak down just enough for sensing link to correct it,causing the whole tractor to shake.The more weight on the hitch the worse it is. This problem started after somebody else removed and installed rock shaft cover to repair another problem.

I agree with Martian, if the repair has a warranty, seek satisfaction from the repairer. If not, it might help to know why it was taken apart and by who. It might be the position feedback linkage needs adjusting or the draft sensing feedback linkage needs adjusting. Last thought, main relief valve is set too high.
my 5410 which shares the same manual so probably the same stuff seems to burp just a little when raising the hitch otherwise it works fine though I have not had need to use the draft yet. Certainly no shaking of the whole tractor. I was hoping there was a bubble in it somewhere but it has yet to cure itslf. As the tractor ages and gets useage more leak down and subsequent correction by the position sensing stuff would seem normal to expect.

They tell me that the original problem was that the hitch would not drop. The owner and a friend removed the cover and disassembled the valve, not finding anything wrong they took it to a dealer, who found the drop rate valve closed all the way. After the cover was installed it had this hitching problem. I question their assembley of the rock shaft valve,but cannot find prints of spool location and/or orrintation because valve is considered unserviceable by JD.I agree with Martian, if the repair has a warranty, seek satisfaction from the repairer.

That's a tough situation. So JD won't service the rockshaft at all, and therefore don't publish the printouts? What do they expect, if something goes wrong with the rockshaft you order a brand new tractor?They tell me that the original problem was that the hitch would not drop.

I think in that case you have nothing to lose taking it apart and seeing if there is more than one way to reassemble the valve. It can be removed without pulling the rockshaft cover.They tell me that the original problem was that the hitch would not drop.

You could at the least pull in new o rings. maybe they missed one.
Have priced a new valve? Might be worth it to fix the problem.
