2013 Illinois Soybean Summit - Marion Calmer (Keynote Speaker)


"We run two combines now, one with Calmer BT Crushers and one that was new to us. We ran 3 to 4 rounds, stopped and walked for 10 minutes. We called and ordered a Calmer BT Crusher Kit for the new head! We didn't run the new head until the Calmer order arrived and was installed."
