The Calmer upgrade kit solves many
of the mechanical problems with the
new holland 980cr corn heads.
These parts enable this head to perform
better than new at a fraction of the cost
of a new or chopping corn head.
100% satisfaction guaranteed!
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.
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 mimics the bottom
portion of the corn ear to reduce
butt shelling problems and trash intake.
Calmer’s new oil bath sprockets
slow down the entire corn head
to help decrease both ear bounce
and butt shelling problems that occur
when the corn head is running too fast.
calmer gathering chain drive and
idler sprockets better synchronize
gathering chain speed with stalk roll
speed to allow cornstalks to travel
efficiently into the row unit.

Follow along with Marion as he explains the Full Calmer BT Chopper® Upgrade Kit offered for the New Holland 980CR corn heads. These patented corn head parts will turn your underperforming factory corn head into a top performing machine while also making you more money in the process by reducing a pass across the field, eliminating the chopping of stalks, improving planting operations, and increasing yields.

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
“We wanted to do some testing ourselves so we ran 1 row of the Calmer BT Crushers, 1 row of brand new Deere rolls, and one row of modified Deere rolls. We would see the rusher rows with no problem. Now we want to go to the Choppers on all 8 rows because we plant beans into corn stalks—It will be even easier with no stalks.”
Reduce Butt Shelling and
Decrease “Trash” Into Combine
Calmer’s Patented Multi-Zone Beveled Stripper Plates are design with a wider front opening to minimize the bulldozing of cornstalks when not fully aligned with the row. This wider retrieving area is manufactured flat 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 also better mimics the rounded corn ear to reduce kernel loss by displacing the energy around the base of the corn ear.
Accelerator gathering chain Sprockets
By speeding up gathering chains by 18% with Calmer’s larger 13-Tooth Drive Sprockets, stalk roll speed is better synchronized to gathering chain speed. This allows for more of the plant to be processed at the corn head and prevents the gathering chain lugs from inhibiting the entry of the cornstalks as they travel into the row unit.
Calmer’s smaller 13-Tooth Idler Sprockets allow for a factory chain to be utilized by maintaining the same chain envelope as factory corn heads.
“The performance of the two rows with the BT Chopper rolls is phenomenal. Thanks for your recommendation at the No-Till Conference. I will get the rest of my rows upgraded with the BT Chopper Trash Reduction Kit this winter. Thanks for helping me get my old equipment up to modern standards.”
– Jonathan Hess
Oil Bath “slow down” sprockets
The stalk roll tip speed on New Holland 980CR corn heads is too fast. This often causes excessive ear bounce and butt shelling problems.
To solve this issue, Calmer invented oil bath sprockets to slowdown the entire corn head, decreasing the ear bounce and butt shelling issues caused by excessive head speeds.
(Oil Bath “Slow Down” Sprockets are not available for NH 980CR folding corn heads or for 20- and 22-inch corn heads.)
