Aside from what goes in the bin, there probably isn't a more important task during corn harvest for no-tillers than making sure residue is properly processed.

It used to be that the primary task of a corn head was to harvest corn: separate the ear from the stalk with as little grain loss as possible, while collecting as little trash as possible, says Marion Calmer, a no-till farmer with Calmer Corn Heads in Alpha, Ill. But as growers look to better integrate field operations, the corn head is playing an increasingly important role in managing crop residue as well.
