We have two nearly identical 9750sts's and on one when you hit the button to raise/lower the header it moves right away, sometimes causeing some bounce. On the other, newer to us, one when you hit the button the header takes a split second to move, it seems to have a delay and when it finnaly moves you are not sure if it moved at all. Either one would be fine because you can get used to anything, but when you useually run one and hop into the other it's kind of a pain. So I guess I am asking if I can adjust the header response on one of them.
