Our 7120 unloading auger will sometimes swing back by itself. It usually happens after swinging it back a bit (say while unloading), though sometimes just the unloading auger shaking the combine is enough to start it moving. I can hold it out with the button, and it moves easily back forward, so maybe it's jut leaking across the valve a little bit. We initially thought the problem was electrical, but we get good action on the solenoids, and the diagnostics display is giving us a good reading on switch position, so it's not in the switch. I can reproduce the problem here in the yard. It seems to not do it right away when the combine is cold, but after things warm up a bit it starts acting up. So I think it has to be in the valve.
Has anyone seen this before? Can I rebuild the valve, or should I just buy a new one?
