Combines 2381 straight head vibration

I happened to operate a 2381 30' head on the front of an 860 MF and my steering column shook day after day. It is the wobble box and unfortunately that is as smooth as they run. Check to make sure there are no cracks developing on the header table around the wobble box. This would exaggerate the vibration. Weld any cracks if needed.

Make sure the stabilizer bars toward the center of the header are tight, and that the bushings are not worn.
