               • Total capacity increase 15% or higher.
    Customer




               • Flatter loss curve to reduce sensitivity at capacity limit.

               • Minimize power requirement for additional separation rotors.

               • Comparable straw quality (bale-ability) to conventional WTS.

               • Minimize amount of new parts by utilizing existing John Deere technology.
    Factory




               • Integrate new separation system into existing WTS chassis concept.
