New KernelStar technology represents next phase in advanced forage processing from John Deere

OLATHE, Kansas (August 23, 2012) – John Deere announces that it will further advance its biomass and livestock feed processing systems through the acquisition of the innovative KernelStar kernel and forage processing technology for self-propelled forage harvesters. The company has acquired the intellectual property rights for the technology from the German company CAWI. The technology has already established very strong customer acceptance for enhancing forage quality for livestock and biogas producers.

“The new John Deere KernelStar technology will add significant value to John Deere Self-Propelled Forage Harvesters and should further improve machine productivity in the field. The integration of this new kernel processor is the result of intensive customer research and reflects the growing demand for the best possible forage and substrate quality,” says Chris Wigger, vice president of sales and marketing. “Following the HarvestLab technology, which has established itself in the last five years as the leading ingredient sensing technology for self propelled forage harvesters, KernelStar is the second pillar of forage technology innovation.”

KernelStar, a state-of the-art concept, is based on a patented “bevel” disc design which allows for more intensive treatment of the kernels when compared to either the conventional cylindrical roll or disc designs on the market. “Apart from the improved processing of kernels, a significant reduction of over-length particles can be achieved, as well as a reduction of the component’s power consumption,” explains SPFH Division Marketing Manager Richard Halsall.

The new design uses contoured intermeshing discs that provide increased surface area to enhance the crop processing. “Due to its patented shape, the discs provide almost three times the effective processing width compared to the conventional roll type kernel processor,” adds Halsall.

Full integration of the concept into John Deere forage harvesters as a factory installed option will be announced later this year. “This new component seamlessly ties in with a number of other industry-leading solutions on John Deere foragers, including innovative header solutions, the DuraDrum cutterhead and the award winning HarvestLab moisture and constituents sensor”, says Halsall.
