BT Chopper Stalk Rolls
Through the integration of multi-length blades,
Calmer Stalk Rolls have a patented “open window”
feeding chamber, which guarantees the efficient
flow of cornstalks into the row unit to
become processed into “confetti-like” pieces
by 20 razor-sharp blades.
Multi-Zone Beveled Stripper Plates
Our patented stripper plates have a wider
front opening to help prevent the bulldozing
of cornstalks when slightly off the row. The
beveled stripping area emulates the bottom
portion of the corn ear to help reduce
butt shelling problems and trash intake.
Slow Down Kit
calmer’s patented “slow down” kit includes
a new drive and idler sprocket combination,
which slows down just the gathering chains by 25%.
This reduces trash intake, decreases kernel loss
and increases the longevity of the sprockets and chains.
Calmer grass knives are designed specifically for
the bt chopper’s redesigned nose cone and
helps prevent the back wrapping of grasses
along the waterways or in heavy vegetation.

AND GRASS KNIVES
Reliable stalk rolls are critical to a top-performing corn head. That’s why Calmer invented the World’s Only All-Weather Stalk Roll™ known as the BT Chopper®, which is the only roll in the industry with a patented “open window” feeding chamber for the superior feeding and processing of stalks in all crop conditions.
The 10 razor-sharp knives on each stalk roll cut, chop and shear cornstalks into confetti-like pieces for accelerated decomposition. As a result, you’ll be able to reduce a management pass across the field, improve your planting experience and increase yields. Calmer Grass Knives match the curvature of the BT Chopper’s® redesigned nose to prevent the back wrapping of grasses.
MULTI-ZONE BEVELED STRIPPER PLATES
“They work just as Marion described – true facts! Saves those small ears you would lose with OEM deck plates and now we have no butt shelling. Calmer’s rolls/kits gets rid of all the husks and now just ears going through the machine.”
Reduce Butt Shelling and Decrease Intake of Material Other Than Grain (MOG) aka “Trash” Into Combine
Calmer’s Patented Multi-Zone Beveled Stripper Plates have a wider front opening that helps minimize the bulldozing of cornstalks when not fully aligned with the row. This wider retrieving area is manufactured straight to reduce ear wedging problems and beveled in the back stripping area to allow the stalk rolls to engage the ear shanks, leaves and husks, which significantly reduces trash intake into the combine. The patented beveled edge emulates the rounded bottom of the corn ear to help reduce butt shelling problems by displacing the energy around the base of the corn ear.
Slow Down Kit Chains and Sprockets
“I have been using Calmer Chopper Rolls and trash reduction kit since 2010. Recently traded heads and the first thing I did was remove brand new JD rolls and put Calmer Choppers on. Since I started using Calmer products I’ve had 5 neighbors update their corn heads to Calmer product!”

By slowing down gathering chains by 25% with Calmer’s smaller 6-Tooth Drive Sprockets, trash intake can be reduced by an average of 61%. Calmer’s larger 9-Tooth Idler Sprockets improve the chains’ grabbing ability in both normal and adverse crop conditions and allows for a standard-size gathering chain to be used. This new-and-improved, non-greaseable idler sprocket is solid-steel and has a replaceable bearing for increased life and lower maintenance. Longer-lasting Chrome-Pin Gathering Chains are sent with all Slow Down Kits.
