To me it would depend on the farm situation. If it just you, or you and few people who are all wanting to grow big mature bucks and are on a big tract of land where the chance of someone else popping him are low then I'd pass him. Id guess he's 3.5 yo. And being in central IL you know theres a good chance theres a bigger one somewhere nearby. But if your in a highly hunted area or on a small tract of land I'd stick em. JMHO Good Luck whatever you decide
