Superior Management

Patented BT Chopper® Stalk Rolls cut, chop, and shear cornstalks into confetti-like residue for fast decomposition, easier planting and higher yields. You’ll reduce a pass across the field simply by running your corn head, saving you time and money.

more grain in the tank

Our Patented Multi-Zone Beveled Stripper Plates reduce kernel loss and mitigates trash intake into the combine, putting more grain in the tank and money in your pocket.

TRASH REDUCING “SLOW DOWN” SPROCKETS

Our patented 6-Tooth Drive Sprockets slow down gathering chains by 25% vs. factory John Deere 90 series corn heads to reduce kernel loss and trash intake. The larger 9-Tooth Idler Sprocket helps the grabbing and conveying ability in adverse crop conditions. 

15inch row size corn head gathering chain

lower maintenance

Our patented single-chain design results in a lighter-weight corn head by eliminating an extra chain, chain guide, idler block, drive and idler sprocket, drive shaft, and chain tension spring. This reduces parts and maintenance.

Realigned Design

Calmer Heads are strategically realigned to reduce ear toss problems and allow for the better flow of material from the tray to the feeder house opening in high-speed harvesting conditions.

HIGH-PROFILE, SHORTER SNOUTS

Our 15-inch poly snouts are among the shortest in the industry to allow the corn head to maneuver through narrow rows and around countoured areas. 

oversized cross auger

Our oversized 18-inch cross auger with a 26-inch pitch helps convey material in the tray at the right speed for an easier handoff to the feeder house chain. We adjust the cross auger to 1 3/4-inches between the flighting and tray to reduce ear slicing and kernel damage cause by improper adjustment.

Bragging Rights:

“I was very impressed with Calmer Corn Heads’ 1615. We harvested our 15″ row corn at 20-28% with the 1615 in both standing corn and down corn conditions. The 1615 was able to minimize the losses of down corn by operating in a non-row sensitive manner and traveling at whatever angle was necessary for those conditions. The 1615 was also equipped with the Calmer BT Choppers® that sized the heavy corn residue, preparing the field for the following planting season.”

Randy Dowdy

Valdosta GA, Soybean yield world champion & 1st farmer in history to raise 500 bpa corn

“We run two combines now, one with Calmer [Stalk Rolls] and one that was new to us. We ran 3 to 4 rounds, stopped and walked for 10 minutes. We called and ordered a Calmer BT Chopper® Kit for the new head! We didn’t run the new head until the Calmer order arrived and was installed.”

David Godfrey/Jim Godfrey

Jonesville, MI

“I picked 1,600 acres of down corn that you could not even see the rows in. I installed Calmer Stalk Rolls on my custom-built corn head, no auto steer, just head control. My agronomy guys were so impressed on how my field looked, how little corn was on the ground, and how the stalks were chewed up.”
