problems from unprocessed cornstalks
and how to solve them at the corn head
Unprocessed cornstalks rob yields by failing to decompose at a rate quick enough to recycle important nutrients back into the soil before the following year’s crop. Calmer’s chopping stalk rolls cut, chop and and shear cornstalks into two halves to expose the pith of the stalk for accelerated decomposition, easier planting and higher yields. The way Calmer BT Choppers® process stalks also helps reduce a management pass across the fields and reduces the need for chopping stalks.

Steps to correct problem
Broken Cobs in Grain Tank
Adjust the top sieve to achieve the desired appearance in the grain tank sample.
Butt Shelling or Kernel Loss
Most likely attributed to stripper plate design or gathering chain speed, watch the videos to solve this problem.
Corn in the tailings Auger
Improper bottom sieve adjustments can lead to corn in the tailings auger. Marion shows you how to fix this problem.
Corn Loss on downhill side
Adjusting your combine's fan speed can help reduce this problem. Watch to learn more.
Cornstalks breaking Off
Excessive gathering chain speed can clip off stalks while entering the corn head. Hear Marion's advice to solve the problem.
Cornstalks not entering row units
Cornstalks cannot travel efficiently into the row unit without a space for the stalk to enter. Currently, Calmer BT Chopper® Stalk Rolls are the only rolls in the industry with this patented design to allow the entry of stalks in al crop conditions.
Cornstalks Not Processed
Cornstalks fail to get processed if they can't enter the stalk rolls. Calmer Stalk Rolls have a special feeding chamber to easily engage stalks to be become processed into confetti-like pieces for fast decomposition, easier planting, and increased yields.
Cornstalks pushed over
Stripper plates, gathering chain speed, and/or stalk rolls can all contribute to this problem. Watch our videos to refine your settings to solve this problem.
Cracked Grain in Tank
Your cross auger, rotor speed and/or sieves could be the culprit.
Ear Separation Problems
Watch our videos to learn how to check your corn head angle, stalk rolls and gathering chain speed to mitigate this problem.
Excessive Stalk Roll Wear
If the corn head angle is too flat, stalk rolls don't perform as effectively and wear faster.
Feeder House Congestion
Learn how to adjust your feeder house chain to reduce the congestion of material at the feeder house.
Harvesting Down Corn
Marion has numerous recommendations for reducing your stress levels while harvesting down corn. Click to visit our entire page of recommendations for a more efficient down corn harvest.
Foreign Material in Sample or tank
Improperly set sieves and fan speed can result in foreign material in the grain tank. Easily solve this problem with Marion's recommendations.
Overloaded Cleaning System
Adjust your sieves to help prevent overloading your combine's cleaning system.
In Case IH Combines, adjust your transport vanes to the slow position (toward the back of the combine). Watch the video to see how.
An improperly adjusted cross auger can result in sliced ears and kernel damage. Learn how to set it properly to reduce this yield-robbing problem.
Small Ears Falling Through Head
Stripper plates are set too wide if this is happening. Learn how to adjust them properly for maximum performance.
Rotor speed helps reduce un-threshed ears. Marion will walk you through solving this problem.
