Cereal high cut
In harvesting technology, the advantage of high chopping is that significantly less straw has to be processed in the combine harvester. This increases the harvesting speed and reduces fuel consumption. This effect is particularly noticeable in high-performance combine harvesters with large working widths, as a correspondingly large amount of straw is produced. Every centimetre of straw that can be left on the field through a high grain cut also has a positive effect on grain drying costs, as the lower part of the grain contains the most moisture.
New technologies for high-cutting grain
Together with Ennepetaler Schneid- und Mähtechnik, New Holland (CNH Industrial) has for the first time developed a professional combine header that combines the advantages of high cutting with those of low cutting (so-called Dual Stream System). This is achieved by combining two cutting units arranged one behind the other. This creates a double cutting process that has a number of advantages over a conventional harvesting process. On a combine harvester with Dual Stream technology, the grain is harvested in two coordinated steps. The conventional cutterbar, which is offset forwards, first cuts the grain at a variably adjustable height (grain high cut) and feeds the crop to the threshing process.
Advantages of high-cutting grain with ESM cutterbars
A second ESM double-blade cutterbar mows the remaining straw synchronously to a stubble height of approx. 12 cm. The stalk cuttings resulting from this second cutting process remain in the field. The result is a clean and low-cut stubble that is excellent for further processing. The double cut of the Dual Stream system makes it possible for the first time to combine a high cut with a classic low cut on a professional level. The result is less strain on the combine harvester during high grain cutting, a reduction in fuel consumption and an increase in harvesting speed. This extremely effective harvesting technology is made possible by ESM bidux double knife cutterbars, whose cutting properties make such a synchronised grain high cut possible in the first place. Low working energy, low-vibration and blockage-free operation and clean cutting results are just as important factors here as the insensitivity of the ESM bidux double knives to foreign bodies.
