Amazone has extended its range of high-performance Cirrus Grand large area seed drills, with the 8 meter wide Cirrus 8004-2C Grand. The trailed cultivator is aimed to meet the demands of large farms and contractors, working with tractors from 280 hp.
Key feature is its precision and flexibility, provided by the simultaneous metering of different products via the new three-chamber hopper with a total capacity of 5,900 liters. Combining three chambers in the one hopper offers a high level of flexibility and easy accessibility for the operator. Up to three different products can be individually metered at a ratio of 40:50:10. For example, rape, fertilizer and slug pellets can be applied in one single pass using the Single-Shoot process. In addition, wheat can be sown together with the simultaneous application of fertilizer and micro-granules. All products are delivered precisely to the same point in the seed furrow, which ensures efficient application.
12.5 cm row spacing
The large distributor head and the choice of the Smart plus equipment level ensures optimum lateral distribution. The individual row shut-off ensures high sustainability by reducing waste of seed and fertilizer on headlands and in wedge shaped fields. Tramline control is provided symmetrically, asymmetrically or flexibly and is selected in a user-friendly manner via the ISOBUS terminal. The distributor head adjusts automatically. This means that the working width of the seed drill is independent of the respective tramline system. Deactivating individual rows offers a particular advantage. For example, rape can be sown with double row spacing.
The Cirrus 8004-2C Grand also benefits from an additional row spacing option. On top of the conventional row spacing of 16.6 cm, a narrower spacing of 12.5 cm can also be specified. This is ideal for spring sowing and farms with high weed pressure. The narrow row spacing allows the crop to cover the soil over more quickly, which reduces weed emergence. This leads to a cleaner crop and decreases the use of herbicides.
The AutoPoint automatic measuring system for determining conveying times, has now been incorporated in the Cirrus 04 Grand. A sensor in the seed coulter determines the conveying time of the seed flowing from the metering unit to the coulter and automatically adjusts the switch-on and switch-off points of the system on the headland. This technology constantly improves the Section Control times and increases sowing precision. This results in the minimization of misses and overlaps, improving field hygiene.
Range of front tools
In addition to the T-Pack front tyre packer, new front tools are also available for the Cirrus 04 Grand. A crush board with outlying guide wheels has been specially designed for farms with heavy or cloddy soil conditions. The crush board levels the surface, breaking up clods and ensuring a level seedbed, especially for use after the plough or following rough primary cultivation work. The guide wheels on the outside of the machine ensure smooth guidance and prevent the wings from sinking into the ground. The Cirrus Grand is also available with guide wheels in front of the disc element for farms that carry out complete seedbed preparation before sowing. This means that there is no need to use a front tool.
Another plus point is the optionally available on-board hydraulic system with a push-on PTO pump. This enables the drill to be operated with tractors with a low hydraulic capacity. The optional air pre-heater ensures trouble-free operation when working in damp air conditions. It increases the temperature of the air flow by around 8 °C reducing the formation of condensation and thus preventing seed dressing or fertilizer dust from sticking in the conveyor system.
These new updates are now also available as options for the Cirrus 9004-2C Grand with its 9 m working width.
