Hey guys, like the title says I have a 2004 John Deere 4110. Machine has only 350 hours on it. Since new it has had a FEL and a 46 backhoe on the back. I recently decided to put a 3 point setup on it to use some rear implements as well. I installed the 3 point setup and as soon as I put an implement on the 3 point I get a really bad non stop bounce on the implement. Adjusting the hydraulic control valve by the Floor board does nothing to stop this nor does it stop the implement from dropping after the tractor is shut off. I’ve been doing a bit of research today and thinking maybe rockshaft valve? Has anyone ever had this problem?
