Will you be switching your combine to run the narrow row headIJ I have been looking for the 13_25 sprockets that run the 4-38 corn head. The sprockets that run the 4-30 head are 13_13. I have the 13_13 sprockets to trade if needed. In addition, there used to be a few descent A-430 heads at Mayer Equipment near Wilmington OH www.mayerfarmequipment.com My e-mail if the sprockets are available is p_and_a77@hotmail.com
