7120 in Corn – Huge Capacity-Hull, IA: I got a call from today from Hull, IA area. They were completely ecstatic about the capacity of a 7120 combine! They were running a 12 row head in 200+ corn and the combine was doing 4700 bushels per hour! This was a instantaneous reading and the corn was yielding good and was on dryer side. However, it is pretty amazing to have a class 7 combine that has this kind of performance. (The combine was setup to run the clean grain elevator on the high side.)
