As a seed dealer, I am always amazed at the number of split planters I see in the spring.  There are many reasons as to why this is not advantageous to you or the products you are working with.  Reason #13 jumped out at me as I was riding in a combine; the operator was harvesting corn that was very high in moisture and was having trouble setting the combine to get a nice clean sample. 

Picture A depicts two different hybrids coming into the combine at the same time.  Note the two different widths of kernels. Picture B depicts two different hybrids with different kernel sizes, yet being combined together. Picture C denotes the two different cob sizes going into the combine. 

A combine is a marvelous piece of technology, however, in these examples a proper setting will be a happy medium between the two hybrids.  As corn becomes drier, the settings are not likely as critical; unfortunately, today we are trying to harvest 30% + corn and needing to maintain quality so we don’t end up with tons of fines. 

By the way, I haven’t even discussed what these split planters do to your dryer settings!
