I would like to know more about this screen. What do you do with it in cornIJ Just finished picking my corn today (first time with this l3). Haven't grown much corn at all till recently here in central Kansas so it was a learning experience to say the least, especially by the time we got an old orange 630 working that had been sitting outside for a few years. Anyway it seemed like I had a lot of cobs going over the chaffer. Shouldn't most of them be going over the walkersIJ Maybe by next year I'll learn how to set everything.
