The saw blades of John Deere rotary crop headers cut quickly and thoroughly at a high speed of rotation. As the fast-turning blades cut the full width, crops can be harvested regardless of the row spacing. Thanks to this row-independent harvesting technology, the field can be worked from any side, which is particularly important for down crop.
You can find more information on our web, so please take a look.
The fast-turning saw blades allow crops with a lot of weeds to be harvested easily. Besides maize, a wide range of crops such as sorghum, whole crop silage, oilseed, canola, pampas grass, and miscanthus can be harvested.
Key features:
After the fast-rotating blades cut the crop, the intake fingers push the plants into the gatherer drums that rotate in the same direction at low speeds. Every plant is pushed into the teeth of the gathering drum. The specially designed shape of the teeth ensures that both small and large plants are conveyed in a secure way.
The new and improved intake finger design allows for the crop conveyance to start deeper into the drum to ensure plants are more securely held prior to cutting, which in turns allows for a clean cut before being guided into the machine while maintaining control of the stalk. Improving the intake area on the 400pro series headers allows for less cob and crop losses during difficult harvesting conditions. The new intake drums with the new tooth design allows for better performance in down crops.
In the machine, the plants are taken off the back of the gatherer drum by scrapers. Depending on the width of the header, they are forwarded to the cross-feed drums or immediately fed into the angled feed drums in the middle of the machine.
To provide an increase in uptime and productivity the 400pro headers also feature a new-style gathering drum. This particular gathering drum allows for the top cover to be removed separately and quickly provide better access to the intake fingers for increased serviceability and easier access for cleaning.
Even feeding of the harvested crop bundled lengthwise to the chopper unit of the self-propelled forage harvester (SPFH) is crucial for an even cut. Only even, lengthwise feeding allows for the full use of the power installed on the SPFH.
Benefits:
Two angled feed drums push the crop toward the feed rolls of the SPFH. The size of the feed drums depends on the size of the header; the six-row headers feature three rings that push the crop in the feed rolls of the SPFH. The eight-, 10-, and 12-row headers feature a lower version with only two rings.
In model year , the middle section will feature a new and longer front cover that protects cobs from being damaged by the gathering drums. In addition, this cover can be removed to assist in harvesting down crops.
Benefits:
With the most recent generation of the small drum headers, leading performance is proven. Due to feed availability pressures, the variety of plants and harvesting conditions becomes more and more challenging. The investment into a special head is expensive. The John Deere small-drum header is a good alternative to harvest a variety of crops.
The most challenging is the optimization of the crop flow in the header. An open construction was the solution. All drum scrapers or holders of divider points are positioned out of the crop flow. An accumulation or blocking of weeds and leaves will be avoided.

Calmer BT Chopper® Stalk Rolls and Residue Management Kits help reduce a management pass across the field, improve planting operations, last longer than factory parts, and increase yields and profits! 100% satisfaction or your money back guaranteed!
In , John Deere & Co. tested their stalk rolls against Calmer’s BT
Chopper® and another aftermarket stalk roll design.
Their tests supported what we’ve been saying all along about the benefits
that make our stalk roll kits the most effective on the market.
John Deere’s tests showed that Calmer BT Chopper® Stalk Rolls have
the lowest gearbox spreader load (stress on pinion shafts) than even
factory john deere stalk rolls.

Calmer Stalk Rolls take a minimal amount of additional horsepower
compared to standard Deere rolls and 22% less horsepower than the
360 Chainroll.
When comparing Calmer Stalk Rolls to rotary-bladed chopping corn
heads, our rolls use 25% less horsepower, are lower maintenance, are
less expensive, and leave stubble that is easier on tires.
Calmer BT Chopper® Stalk Rolls cut, chop and shear cornstalks into the
smallest pieces in the industry for fast decomposition, easier planting,
and higher yields.

A study from the University of Illinois’ Department of Crop Sciences found that Calmer BT Chopper® Stalk Rolls increase continuous corn yields by an average of 6 bushel per acre when compared to OEM stalk rolls.
Image A) Standard stalk rolls fail to engage and process stalks properly, resulting in additional management passes and lower yields due to nutrients being immobilized on the soil surface.
Image B) Calmer BT Chopper® Stalk rolls chop stalks into small pieces while simultaneously exposing the inner pith to recycle critical nutrients back into the soils faster, resulting in faster degradation rates and higher yields.
The University of Illinois study showed the way Calmer BT Choppers® size cornstalks increased corn on corn yields be an average of 6 bushels per acre!
By exposing the inner pith of the stalk, the Phosphorus, Potassium, and Nitrogen applied to grow the crop are recycled back into the soil instead of remaining immobilized on the soil surface.
Seedling emergence in continuous corn was significantly delayed during the first 5 days of emergence (3-26% delay across harvest method; P= 0.007) compared to corn in rotation with soybean. Stand establishment was reduced in corn on corn vs. corn following soybean (94% vs. 97%, respectively)
Allow the natural elements to work for you toward breaking down cornstalk residue. The study showed that cornstalks sized by Calmer BT Choppers® degraded 7% faster than residue managed by factory stalk rolls.

With Calmer Products, you’re getting more than just corn head parts, you’re getting a peace of mind that your residue management and corn head problems are solved for good during harvest.
Because our products are farmer invented, farmer tested and farmer proven, everything comes with a 100% Satisfaction or Your Money Back Guarantee. Having been voted to the No-Till Product of the Year list five times, farmers across North America continue to rely on our award-winning technology to solve their residue management and corn head problems. Because customer demand continues to grow each year, call early in the season to place your order and calculate the return on investment you’ll see from your acreage.
We generally see 500- row acres. Simplifying that out for example, projected life expectancy for BT Choppers® on an 8-row corn head would be between 4,000 and 8,000 acres harvested in total. Life expectancy is maximized when following Calmer’s recommended corn head angle settings.
Yes – definitely, and that increases the value of your investment. We publish the installation manuals and provide support for questions that may arise.
No. Installing Calmer BT Choppers® by themselves will yield positive results and increase your corn heads performance; however, installing Calmer’s entire upgrade kit will result in maximum performance.
