We ran one at Watson for 5 days with our 9070s. Differences were horse power, extra rad, braced rotor drive clutches like on 9080, supposedly a larger gap from grain pan to presieve to allow higher wind speeds to help seperate seed and chaff. Feeder house and everything else was the same. We were runnning in 50-60 bus canola in november (damn tough) at between 4 and 5 mph. Rarely over 5. Usually about 1mph faster than 9070s. 20 - 25%. Liked fuel too, but i've heard its about the same as 9080 on fuel but higher performance due to compound turbos. Also has electric folding grain tank cover standard from factory, like lexion. It was impressive!
