With 1800 rpm, the accelerator provides sufficient thrust to the crop stream for secure overloading with the largest of heads without consuming excessive power. All components that have an acceleration impact on the crop perfectly integrate tangentially into this curve for a fully unobstructed crop flow. The crop accelerator, the spout transition, and the spout build the machine’s crop discharge device. The crop path follows a constant curve between the cutterhead floor and the accelerator entrance. The crop mat is perfectly compressed until the last second before transitioning into the knives.įrom the moment the knife pockets start unloading, the cutterhead band takes the crop particle stream, collecting it for launching into the crop chute. On its way to the cutterhead, the radial-arc-feed roll arrangement applies pressure to the crop for superior cut quality. This is a key function when corn headers without feed augers are mounted, assuring the machine’s crop feeder is the sole length-of-cut (LOC) metering unit of the harvester. Key characteristics are a set of front feedrolls where, when the header interface is in a vertical position, the upper-front feedroll (UFFR) reaches out about 60 mm (2.4 in) over the crop in front of the lower one, grabbing the mat from the harvesting header and pulling it into the feedroll gap. John Deere has implemented a concept layout well proven on the 7000 Series. On the actual harvester, it starts with the feedroll arrangement.
FS13 FEEDING COWS SERIES
The 8000 Series cropflow channel begins at the harvesting unit pickup tines or crop-row pointer. Longer component wear life significantly lowers the cost of ownership.Ī key concept for the 8000 Series Self-Propelled Forage Harvester (SPFH) line was to position all crop-flow components to avoid any flow obstacles, as well as to design the crop path for minimum kinetic friction on the particles. Most advanced wear-resistance technology is applied on all crop-flow elements to assure full-season harvesting uptime.

Specific component design has been implemented to overcome any efficiency compromises that could derive from applying a certain driving method.Ĭomponents have been laid out for matching the power demand, not only of today’s producers, but also meeting potential requirements of future users. The driveline concept has been optimized for maximum flexibility in setting the individual component speeds and also synchronizing certain functions for maximum harvesting quality. As the existing configuration of the 7000 Series maxed out, a key demand on the 8000 Series was to find a machine layout for optimum weight distribution and maximum capacity potential. Machine size, weight, or soil compaction associated with weight, and tire size are critical to producers' acceptance of a certain machine on their fields. Relative emphasis has the advantage to consider that traits are not estimated with the same reliability and have different ranges of genetic variation, being particularly beneficial when adding new traits with high economic importance and low reliability, such as Feed Saved.Capacity, harvesting quality, machine efficiency, and total cost of ownership have always been important differentiators for self-propelled forage harvesters (SPFH). Illustrating the relative emphasis given to each trait in the formula, as shown in Figure 2, is a new way of expressing the index, compared to the relative economic value that has been published previously to reflect the actual economic importance of the trait.

The relative emphasis shows the contribution of each trait when ranking the animal on the NM$ scale.

The document can be found at on./netmerit. Details about the revisions to all four indices can be found at or in the official document, “Net Merit as a measure of lifetime profit: 2021 revision,” written by Paul VanRaden and co-authors at CDCB and USDA’s Animal Genomics and Improvement Laboratory (AGIL). The other selection indices published by the CDCB for specific production systems - Cheese Merit (CM$), Fluid Merit (FM$), and Grazing Merit (GM$) - will also be updated in August 2021. What traits are emphasized in the new Net Merit? Figure 2 shows the relative emphasis given to each trait in the NM$ formula, expressing traits that we select for (positive weights) in green and traits that we select against (negative weights) in orange.
