INTRODUCING CALMER CONCAVES

MOVING INSIDE THE COMBINE
For the first 20 years of research Marion focused on applying the scientific method to corn head performance that resulted in the BT CHOPPER® stalk roll with over 25 unique patents. For the last three years Marion’s research team has focused on identifying the causation of threshing problems, and testing possible solutions. With over 10,000 tests we are proud to introduce a product that improves performance issues, and we’ll show you how in the videos below!
