    I think you are talking about the pressure control knob that controls the three point lift. If you lower an implement with this valve all the way open the implement will drop like a rock to the ground. If you try to lower an implement with this valve all the way closed it won't lower at all. You can play with it with an implement attached to get the setting correct.
    I used to do the Hokey Pokey but I turned myself around.

    Be careful. Knob all the way open will slam the bush hog to the ground. Better to start knob all the way closed. Tiny steps.

    The knob will also lock the implement in the up mode for transport.

    Also used to trouble shoot the piston seals in the 3pt.

    If you raise the implement and turn the knob closed, and the implement still falls, then the piston seals are leaking.

    This!

    In fact, it's a really good idea to lock the implement in the up position during transport. Some manuals will warn you that damage can occur if you fail to do so.....probably depends on how the system is made, and where the lock is in the system.
