OPERATION CORN HEAD ANGLE NEEDS TO BE ADJUSTED BETWEEN 23 – 25° FOR OPTIMUM DEVASTATATOR PERFORMANCE. USE THE 5000-455 TO CHECK CORN HEAD ANGLE: - Put the combine on a level surface. Lower the Corn head to your normal working head height. - Place the magnetic protractor on the stripper plate to get the angle.
STORAGE/TRANSPORT - Head cart may need adjusted to fit the head with devastator correctly. E.g. raising or fore/aft adjustment of saddles/top rail on the head cart. - If head cart does not have these adjustments, adding a tube extension to top rail or adding extension to saddle/corn head may be required. - Side to side tilt may need used to clear taller head cart tires or locking the devastator up.
