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.

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. Capacity, harvesting quality, machine efficiency, and total cost of ownership have always been important differentiators for self-propelled forage harvesters (SPFH).
