The reason I asked, modifications were_have been made to the Cat lexions threshing, separating, cleaning system and grain handling systems to enable them to better handle higher volume crops like corn, which are not common in Europe, other than wheat. The differences between the Cat lexions and the Claas Euro lexions are extensive. The Cat lexions have been modified to enhance their productivity in not only higher volume North American crops like corn and soybeans, but North American small grains too (rice, barly, wheat, and pulse crops too).
