New Holland 98D Series corn heads
The Calmer upgrade kit solves many
of the mechanical problems with the
New Holland 98D corn heads.
The kit enables your corn head to perform
better than new and at a fraction of the cost
of a new or chopping corn head.
100% satisfaction guaranteed!
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 reduce the bulldozing
of cornstalks when slightly off the row. The
beveled stripping area emulates the bottom
of the corn ear to help reduce
butt shelling problems and trash intake.

New Holland 98D
Follow along with Marion as he explains the Full Calmer BT Chopper® Upgrade Kit offered for the New Holland 98D series corn heads. He describes in detail how the Calmer Upgrade Kit is one of the most advanced corn head systems in the industry that will note only enable your older John Deere corn head to perform better than a new head, but also make you more money by reducing a pass across the field, eliminating the chopping of stalks, improving planting operations, and increasing yields. We guarantee your satisfaction or your money back!
follow our recommended steps for maximum performance
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 faster residue breakdown. As a result, you’ll be able to reduce a management pass, 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
“I’ve been running Calmer’s Trash Reductions Kits since 2004 and have never had to stop for trash. Never having to stop once in all that time, I feel has increased my productivity 25%-30% due to the combine not having to sort through all that trash. It’s incredible running 6 mph while picking 200 b/u corn!”
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 designed flat to reduce ear wedging and beveled in the back 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 mimics the rounded bottom of the corn ear to minimize butt shelling problems by displacing the energy around the base of the corn ear.
gathering Chains and Sprockets
– Mike Shaw, Ogden, IA
Calmer’s larger 9-Tooth Idler Sprockets improve the corn head’s conveying ability of material and allow for a standard-size gathering chain to be used. This durable non-greaseable idler sprocket is solid-steel and has a replaceable bearing for longer life and lower maintenance. Tough Chrome-Pin Gathering Chains and 7-Tooth Idler Sprockets are shipped with all Calmer Kits.
No Feeding Chamber
No stalk roll will perform properly without a feeding chamber in the entry area. All factory New Holland stalk rolls have the same length flutes which causes a continuous overlap in the entry area and prevents the the entry of cornstalks.
Mechanically, this flawed design results in the premature wear at the front of the stalk rolls while the remaining length of flutes remain in good condition since stalks cannot enter the row unit.
Patented “Open window” Feeding Chamber
Through in integration of multi-length blades, the Calmer BT Chopper® Stalk Roll is the only stalk roll on the market with a patented “open window” feeding chamber that enables corn stalks to travel efficiently into the row unit to become processed.
This design performs in all crop conditions, guarantees the traction of stalks for processing, results in longer stalk roll life, reduces low ear snap, and prevents the bulldozing of stalks at the end of the rows.
Limited Residue-to-Soil Contact
Factory New Holland stalk rolls prevent cornstalks from engaging properly with the flutes to become processed. This hesitation results in stalks and ears passing below the corn head without being managed.
Failing to properly process cornstalks prevents residue-to-soil contact, leading to the immobilization of important nutrients on the soil surface, slower degradation rates and a wet mattress of residue in the spring.
Cornstalks failed to enter the knife chamber, resulting in little residue-to-soil contact and slow decomposition rates.
10 intermeshing Razor-sharp blades
Superior Residue-to-Soil Contact
During rotation, the shortened flutes on the Calmer BT Chopper are timed to create 2, 4-inch feeding chambers for an efficient handoff of the stalk into the 17 1/2-inch knife chamber to be processed.
Once the stalk is in the knife chamber, 20 intermeshing, razor-sharp blades cut, chop, and shear it into confetti-like pieces. This exposes the pith of the stalk and places the residue strategically over the row for superior residue-to-soil contact, accelerated decomposition, easier planting and higher yields!
Cornstalks are easily engaged and processed for superior residue-to-soil contact and rapid decomposition..
Straight STRIPPER PLATES
Factory New Holland 98D stripper plates are not formed to match the natural shape of the bottom side of the corn ear, which causes kernel loss upon impact by displacing all the energy on one kernel. (see image below)
This design also fails to allow the ear leaf and the ear shank to get close enough to the stalk roll blades to process them at the corn head. This results in the husk staying attached to the ear and sends it and more material other than grain (MOG) into the combine.
Straight stripper plates don’t mimic the bottom of the corn ear which causes butt shelling problems and increases trash intake.
Patented Multi-Zone Beveled Stripper Plates
Calmer Stripper Plates mimic the bottom portion of the corn ear to reduce kernel loss and trash intake.
