BT Chopper® Stalk Rolls

The World’s Only All-Weather Stalk Rolls™, Calmer BT Choppers® cut, chop, and shear cornstalks into confetti-like pieces for superior residue management capabilities.

MULTI-ZONE beveled stripper PLATES

The unique design of our stripper plates reduces kernel loss and 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. 

Trash Reducing sprockets

Calmer’s patented 6-Tooth Drive Sprocket synchronizes gathering chains with stalk rolls to reduce trash intake into the combine. Calmer’s oversized 9-Tooth Idler Sprocket is solid-steel with a replaceable bearing for longer wear life and improved conveying ability of material in adverse crop conditions. 

15inch row size corn head gathering chain


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. Calmer’s Ultra High Molecular Wright (UHMW) ear guide forms a retaining wall to maintain engagement of the ears with the over-sized gathering chain paddles. This design also decreases maintenance by eliminating half of the parts vs. dual chain heads.

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.

high-profile, shorter snouts

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

Oversized Cross Auger 

We install an 18-inch cross auger on all custom-built corn heads. The 26-inch pitch on this oversized cross auger conveys material in the tray at the right speed to ensure an efficient handoff to the feeder house. We strategically adjust the auger to have a 1 3/4″ clearance between the flighting and the tray to reduce ear slicing and kernel damage. 

30-Inch Rows

The most popular and traditional row spacing, our 30-inch corn heads are equipped with the entire Calmer Upgrade System and will be ready to tackle whatever harvest throws at it.

20-Inch Rows

The demand for 20-inch corn heads continues to grow as farmers look for a yield advantage vs. traditional 30-inch rows, but want the flexibility to side-dress which is difficult in 15-inch corn.

We also build 22- and 24-inch heads.

15-Inch Rows

As the maker of the world’s first 15-inch corn head, we know how to manage narrow-row corn. This corn head is row indepdendent meaning that it can pick in any direction. The single-chain design results in a lighter, lower maintenance corn head.
