John Deere only has four risers per walker while Kuchar has six. The risers sit in the center of the walker, this moves the material twice as fast in the center of the walker than it does on the outside edge. The result is better seperation and less grain loss over the walker. Material is tumbled twice and torn apart, which allows for easier and more efficient seperation. The factory installed risers, however, provide poor fluffing action leading to less than adequate seperation. Sizes fit 9500 and 9600 style John Deere.
