INSIDE X9 - Residue Management

There's a choice of a high performance premium chopper with 124 knives operating at 3,000 rpm and a deluxe chopper with 68 knives and a lower speed of 2,400 rpm. In chopping mode, both the straw and chaff are channeled through the chopper, eliminating the need for a separate chaff spreader and saving energy. The knives feature small dimples like a golf ball. These significantly reduce the air resistance and their self sharpening effect further improves energy efficiency when dropping. The straw makes its way over the top of the chopper and is formed into box like windrows for rapid drying. Chaff is directed away to the sides so the windrow sits on top of the stubble. This allows the baler pickup to be set to a higher position for faster baling without the risk of picking up stones. Both choppers feature the Powercast spreader, which has two mechanically driven discs mounted low. It can distribute residue evenly over the full width of the header, even in windy conditions.
