Advanced C-Series Separation lets you harvest more per day, even in punishing conditions<br />

Stage 1: Threshing<br />

Crop mat enters through a large cylinder and a<br />

750 mm long concave. With 13 bars, the concave<br />

provides aggressive threshing in tough,<br />

hard-to-thresh crops with minimal grain and straw<br />

damage. The “open web” design allows more grain<br />

to fall through the openings; an open transition to<br />

the beater prevents wrapping and slugging. The<br />

result: smooth feeding in green and diffi cult<br />

conditions including non-cereal crops.<br />

Stage 2: Overshot beater<br />

By using an overshot beater the C -Series combine<br />

is able to maintain straw quality with high output.<br />

The unique overshot beater design allows crop to<br />

progress smoothly from the concave and cylinder<br />

into the twin tine separator. There are no sharp<br />

changes in crop direction thus straw quality is<br />

maintained.<br />

Stage 3: Separation<br />

As the crop mat spirals rearward, it’s vigorously<br />

combed by two counter-rotating tine separators.<br />

These provide a pinch-and release action that<br />

frees grain trapped in the straw and dramatically<br />

reduces grain loss. It also minimizes power<br />

consumption. The side-by-side separator design<br />

provides a wide opening that accepts a large<br />

volume of incoming crop. Because the tine<br />

separators assist in threshing, you can lower the<br />

cylinder speed, widen the concave clearance and<br />

boost your grain quality and performance.<br />

Stage 4: Discharge<br />

Crop material fl ows smoothly and evenly into the<br />

positive discharge beater. Whether you’re<br />

chopping or spreading, no matter how demanding<br />

the harvesting conditions, you can depend on<br />

outstanding performance with virtually no<br />

plugging. High-performance, compact design that<br />

reduces slope sensitivity while delivering perfect<br />

results – proving again how our intelligent design<br />

makes a difference for you.<br />
