Corn Head Angle

The right angle of attack improves wear life and effectiveness of the stalk rolls. Park the combine on a level surface and lower the header until the lowest point of the row unit is approx. 2-inches above the ground. Place a protractor on the plates to measure the angle. Try to achieve 23-25 degrees in standing corn. 

Gathering Chain Speed

Begin calibration with initial gathering chain speed of 55 RPM.  If you are seeing butt shelling, slow down the corn head until it starts to bulldoze cornstalks then speed back up until bulldozing stops.

Cross Auger Adjustment

Fine tune your cross auger to prevent ear slicing and cracked grain. Adjust vertically to have 1 3/4-inches of clearance between flighting and the tray. 

Stripper Plate Gap

Pull a stalk from the field to test your stripper plate gap. Ensure the stripper plates are wider than the the third cornstalk node from the brace root. Watch our video for full settings. 

Feeder House Chain

During your pre-harvest maintenance routine, adjust the feeder chain to maximum length and as close as possible to the cross auger. Run at maximum speed to reduce the potential of ears piling up during the handoff from the corn head to the feeder house. 

Rotor Speed

Increase your combine's rotor speed until you can see the first cracked kernel in the grain tank then reduce speed by 10RPM.

Fan Speed
in Corn

Increase fan speed until the red chaff and pieces of broken leaves are no longer showing up in the grain tank.

Case IH
Transport Vanes

Adjust transport vanes to the slow position (bottom of the vanes to the back of the combine). This will reduce kernel loss from the rotor area.

Client Testimonials

“Definitely makes harvest go smoother. Takes in less trash so you are able to go faster without machine loss out the back of the combine. Tops of the stalks look like an M-80 blew up so moisture can start the breakdown process.”

Dion Buhl

Osceola, NE

“Aerial seeded cover crop wheat program in their area. “The wheat flown on a week ago, and the residue from the Calmer BT Chopper is covering the seeded area perfectly as I pick corn. No need for a vertical tillable tool because it is covering it, so I am done. The Grainery noticed the clean grain with no trash.”

Tom Bishop

Chesapeake Bay, MD

“We are on an organic farm and it is extremely important for us to manage our residue in order to have good mechanical weed control for the next year. Calmer parts have made this much easier to do. Thank you!”
