I have a customer that had this done to his 20ft. 500 Series grainhead by Marshall Enterprises (815-866-0029) Night and day difference in feeding with a factory installation look. There is another company that advertises the conversion called AMS limited (217-971-6532).Can't remember the cost for the conversion but still feel this should have been a factory option from the beginning.
