i think you'll be pushing it if you get into a real good yield! we plugged a7700 that was cranked up with a 20' but it was in wheat that believe it or not ran 113 bushels and made about 100 bales of straw to an acre! but only had 6 acres of it ! hey if you would be interrested in a great 920 that has only 1000 acres on it we have one for sell ! got newer combine and bigger head it also has the trailor with it ! hope it works out for you !
