Calmer Corn Heads – Superior by Design

By design, Calmer Corn Heads help maximize your profit potential by enabling you to harvest faster and more effectively than ever before! Here's how:


Our patented single chain design in combination with our low profile, super short poly hoods and dividers result in one of the lightest row units in the industry. 

Multi-zone Combo Stripper Plates

The unique design of our stripper plates helps reduce ear wedging and allows our patented BT Chopper® stalk rolls to engage more corn leaves, shanks and husks in order to reduce trash intake and minimize horsepower requirements. Our stripper plates' elongated design allows for more efficient harvesting of low hanging ears in down corn.

Calmer's Patented BT Chopper® Stalk Rolls

Calmer's patented BT Chopper® replacement stalk rolls chop, cut and shear cornstalks into confetti for truly unrivaled residue management capabilities.

High-Profile Shorter Snouts

Among the shortest on the market, our high-profile, shorter snouts make it easy to maneuver through narrow rows and around tight contoured areas.

Strategically Realigned

Calmer Corn Heads are realigned to allow superior material flow from the tray to the feeder house, reducing ear toss and allowing for maximum flow in high yielding and high-speed harvest conditions.

6-Tooth Drive Sprocket

The Calmer® 6-Tooth Drive Sprocket slows down gathering chains by 25%, reducing trash intake by as much as 60%.

Single Chain Design w/Polyethylene Ear Guide

Calmer's UHMW (Ultra High Molecular Weight) polyethylene ear guide forms a retaining wall to maintain engagement of the ears with the enlarged hardened steel gathering chain paddles. By utilizing Calmer's single chain system, the second chain, chain guide, drive sprocket, drive shaft, idler block, idler sprocket and chain tension spring are eliminated, significantly reducing weight and maintenance.

"About 10 acres in I decided that I had silage for residue, not confetti! I thought I would be getting a stalk stomper, but no need because the stumps are only 6" with exploded tops."
