Intake fingers push every plant into the gatherer drum

Plant pushed into the gatherer drum

After the fast-rotating blades cut the crop, the intake fingers push the plants 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 specially designed shape of the teeth ensures that both small and large plants are conveyed in a secure way.

In the machine, the plants are taken off the back of the gatherer drum by scrapers. Depending on the width of the header, they are forwarded to the cross-feed drums or immediately fed into the angled feed drums in the middle of the machine.

Key feature:

• Every plant is individually and securely pushed into the gatherer drum (Performance).

Lengthwise feeding provides an even cut

Bundled, lengthwise feeding toward the feed rolls

The header bundles the harvested crop perfectly and feeds it to the chopping unit of the self-propelled forage harvester (SPFH) lengthwise for an even cut. Only even, lengthwise feeding allows for the full use of the power installed on the SPFH.

Even chopping of the crop

Key feature:

• Bundling of lengthwise stalks is the basis for perfect chopping quality (Performance).

Deflector plates (purple) on the header

Additional deflector plates (purple) guide the crop toward the blades. This results in a more even stubble height.

AHC sensors on the header

The AHC sensors are located at the two outermost points from the header. The sensors continuously scan the ground and quickly adjust the height and inclination of the attachment. This quick adjustment guarantees a constant stubble height. 

The AHC sensors are optional equipment for eight-, 10-, and 12-row machines. 

Third height sensor on the header

For eight-, 10-, and 12-row machines, the third sensor is optional equipment. The third sensor is only available in combination with RowSense© system as it is installed in the central RowSense pointer.

The two-sensor Advanced Header Control (AHC) does a good job in most conditions. The optional third sensor is needed in extremely uneven terrain or on wide headers.
