After the fast-rotating blades cut the plant, the intake fingers push the plant into the gatherer drums that rotate in the same direction at low speeds. Every plant is pushed into the teeth of the gatherer drum. The special-designed shape of the teethÂ ensures that both small and big plants areÂ conveyed in a secure way.
In the machine, the plants are taken off the gatherer drum at the back of the drum by scrapers. Depending on the width of the header, they are forwarded to cross-feed drums or immediately fed into the angled feed drums in the middle of the machine.
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.
The fast-turning saw blades allow crops with a lot of weedsÂ to beÂ harvested easily. BesidesÂ corn, a wide range of cropsÂ such asÂ sorghum, whole crop silage, oilseed canola, pampas grass, and miscanthus can be harvested.
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 feedingÂ allows forÂ the full use of the power installed on theÂ SPFH.
