Hey, We had 3000 acres of wheat and barley this year and our combine cut 1500 acres of that, while the two other machines cut the other half. They would run one or two hours shorter then us in a day, but there is two machines compared just one of ours. Also, the Deere and the Case are class 6 machines so it should be fairly comparable to a class 7 machine. We all had problems with our machines, but not such big problems that took over a day.
