There is a “breakable fuse” under the header. Protection for the header and combine should you catch something with the header.
If broke you replace it and with header down rock the tilt back and forth until you hear a Big Bang. The arm and rubber bumper get bound up when the fuse breaks and nothing works right until they fall back into proper position.
This is what I mean by my previous post. If the bolt is hitting the frame it's likely that she's broken and the header frame has pushed back against the adapter.
If you need to you can still keep running by pushing the header down onto the ground a bit, and jimmy the tilt fore/aft and side to side till it pops. Then you'll be good again till you get too vigorous and it acts up again. Sometimes it works fine, others not so much.
