Calmer Corn Heads was founded by Marion Calmer, a farmer, inventor and researcher from western Illinois who has pioneered the planting of narrow row corn. He invented the world’s first single-chain, narrow row corn head for 12- and 15-inch rows, built the world’s largest corn heads and is founder of Calmer’s Ag Research Center – the largest privately funded, farmer-run ag research center in the U.S.
As the residue management specialists, Calmer Corn Heads is committed to providing solutions to a variety of your planting and harvesting problems. As a testament to that commitment, in recent years, Marion invented the BT Chopper Stalk Rolls and residue management upgrade kits, which cut, chop and shear cornstalks into confetti-like residue for unmatched decomposition. Having been name to the No-Till Product of the Year list 5 times, these rolls and kits are easy to install, compatible with most corn heads, work with all tillage systems, and are a fraction of the cost of a new corn head. Experience unrivaled residue management performance and newfound peace of mind. Guaranteed or your money back.
