6 row corn head 180bu corn 20ft flex with air reel 90bu wheat & 50bu soys. Question is will the 9400 run this comfortable or should I scrach up a little more $ and find a 9500? Gently rolling land, same as everyone else a tad wet some years. Would like to cut beans around 4 to 4.5mph corn 4mph and wheat 2.5mph. P.S. the 9400 im looking at has the 414 engin.
