The JD 4010 doesn't have a position control for the 3 point hitch, it's strictly a lift/lower affair. Move the lever one way to raise it, the other way to lower. Soon as your release the control lever, the hitch should stop an remain in that position till again you move the lever..
It's a antiquated design, but it's been used for many years on tractor an works well once you get used to it. What it comes down to is it saved Deere a few bucks.. ..
