just for comparison. I run a 9250 with a 45ft head. Had a friend help me with a 7120 and a 40ft head. We were doing wheat from 25 to 70 bu, with average at 45... In a 14hr actual harvest period, I gained 95 acres on him, while keeping my machine at 85% power or less. Anything over 85 and yield goes to hell fast....
