I figured they'd all stay up if everything was working properly. Does the same hold true for the 3 point?

My experience is that the HPL valve and cylinder seal for the 3PH are much better than the cylinder seals and joystick valves for FELs. I would expect your 3PH to drop only slightly overnight under load, maybe an inch or two at most. A local Case/Farmall tractor sales lot put a round bale on a 3PH spear and left it lifted and holding for a couple of weeks. In the same time, an empty FEL bucket was lifted high and drooped within a few days. There seems to be a big difference in the tolerances on these systems. If your 3PH leaks down badly, it will "hiccup" as the HPL valve's position control will sense the change and correct it.

Interesting. Thanks for the info!
