Half-width shut-off and operation through an Isobus digital communications between implement and tractor are among updates for the latest Amazone Citan-C air drill.
The trailed machine is available in 12m and 15m (39 ft and 49 ft) widths for high-output sowing once seedbed cultivations have been completed. It also gets the ability to handle up to 3 different commodities and an upgrade for the disc coulter design.
At the heart of the Citan-C drill is a long, slim hopper that in its latest iteration is pressurised for consistent flow to the metering system and divided into 3 compartments. It can therefore carry up to 8,000 litres (282 cu ft) of seed, a combination of seed and fertiliser brought together in transit to the coulter, or a combination of different seeds – such as a cover crop mix.
The 3 metering rollers are driven by electric motors for variable rate control, and half-side shut off operated manually or by gps section control is standard. Now that Isobus-compliant electronics have been installed, the drill can be operated through a universal terminal from Amazone’s own selection, a third party device or the built-in display on a tractor.
Selected setting-up functions, including calibration, can also be handled using the Twin-Terminal mounted on the front of the machine, where there is also a hand washing facility. RoTeC pro S single-disc coulters with have been adopted from the Amazone Cirrus as standard equipment for the Citan-C. Specifications include a 400 mm (16 in) Boron steel disc with clip-on Control 10 plastic depth limiting discs alongside and greater – up to 65 kg (143 lb) – down-pressure. This coulter, which has a narrower furrow opener than the version used previously, is better able to cope with significant amounts of surface trash and soils that are either damp and sticky or hard and dry, say Amazone engineers.
