The Calmer upgrade kit solves many
of the mechanical problems with the
case ih 4000 series corn heads.
These parts will enable your case 4000 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 emulates the bottom
portion of the corn ear to help 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.
Case IH 4000
Follow along with Marion as he explains the New Calmer BT Chopper® Upgrade Kit offered for the Case IH 4000 series corn head. These patented corn head parts have been upgraded to fit the newer 4000 models to enable it to perform better than new. Improve your corn head’s performance 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 factory nose cone to prevent the back wrapping of grasses.
MULTI-ZONE BEVELED STRIPPER PLATES
“An absolute must for no-till farmers to manage corn residue. Best investment ever for my operation concerning corn harvesting.”
Reduce Butt Shelling and
Decrease “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 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 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.
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.
“We put the Calmer BT Chopper on our 2208. Half way through Harvest, we purchased a 2212. We were so pleased with the performance of the Choppers that we put the ones off the 2208 onto the 2212, and hurried to pick up the extra 4 rows needed from Calmer. These work extremely well!”
– Eldon Hermunslie
Oil Bath “slow down” sprockets
Factory Case IH 4000 series corn heads run too fast. This often causes excessive ear bounce and butt shelling.
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 Case IH 4000 folding corn heads or for 20- and 22-inch corn heads.)
