I don't know if you've got a 2WD or 4WD, but I just bought a 9600 and when I was talking with the dealer, he said some of the 9600s were shipped out with the rear axles bolted in top set of holes in the rear axle frame. He said that if you bolt the axles in the bottom set of holes it will raise the back end of the combine and keep from blow as much out the back. Maybe something to look into to.
