MD3, if you mean the self adjust rate for how fast/slow the 3pt arms react to hydrolic control, that is beneath the driver's seat.
No that is not what I meant to relay. I should try to explain myself a little better. Say the tractor is running and a Bush Hog is mounted on the 3 point. Put the tractor in park and raise the Bush Hog. Now get off of the tractor and watch the Bush Hog start to drift slowly downward maybe about 1? Now I hear a vvvvvp and the Bush Hog raises back up that 1 it lost.
