We have looked the feeder house chain over and do not think its that because with the 1010 grain table on it feeds fine just issues with the row head. The Sorghum will bunch up right behind the auger fingers and acts like it is not being pulled in by the feeder house chain.... We have tried extending the auger flighting, fadjusting the finger position, and we were wondering if the platform drive is variable speed if the head needs to be running faster to throw the material up onto the chainIJIJIJ Any Help Appreciated thanks for the previous postings!
