I have two small fields of sunflowers, totaling about 100 acres. First year to try sunflowers, but, supposedly, they look Ok. Anyway, I have a 2188 combine with a 1020 flex head, and a 1083 corn head. I have read where you can get "pans" for your regular head, and/or do some modifications to your corn head, thus being able to use either. With the limited amount of acres I have, which would be the best, cost effective, solution? Or, another question, could you use the flex head without adding anything?
