COMBILINER SITERA multi-purpose mechanical seeding combinations are equipped with double-disc SEEDFLEX seeding units placed in two rows (35cm offset) for precise and fast seeding. The SEEDFLEX coulter bar ensures unparalleled seeding accuracy, easy passage in all soil conditions, and exceptional seeding performance in both ploughing and min-tilled land. The large clearance of 35 cm facilitates the passage in the presence of plant debris and in difficult conditions. The ground pressure ensures exceptional stability of the seeding units and the press wheels allow the control of the seeding depth row by row by promoting the soil/seed contact for a quick and dynamic emergence. The opening angle of the discs is reduced in order to avoid soil disturbance and to facilitate furrow closing even at high groundspeed. With the SEEDFLEX coulter bar, you give each seed a chance to succeed!
The HELICA distribution flutings of the SITERA mechanical seeder ensures perfect positioning and application rate control regardless of the size and shape of the seed. HELICA is an accurate and reliable distribution system throughout the seeding campaigns. Volumetric metering flutings from 1.5 kg to 450 kg, irrespective of the terrain of your field. Insensitive to vibration, the HELICA distribution respects the seeds of all sizes and shapes.
The seed application rate is adjusted by a single micrometric screw opening the flutings. Result: an extremely precise adjustment for a constant application rate. With the COMBILINER SITERA mechanical seed drill you improve the regularity of low seed rate seeding, such as oilseed rape, thanks to the already integrated “small seed” grooves and you change seeds at a glance and without having to manipulate the distribution.
With a maximum capacity of 1480 litres, the hopper of the SITERA mechanical seeding combination reduces downtime during seeding operations and avoids untimely reloads. You can seed up to 7 hectares of wheat without having to stop to reload the seed drill. It’s an exceptional time saver! Loading by bucket or big bag is facilitated by the large clearance of the hopper lid which opens at 110 °. The assistance provided by the gas cylinders facilitates the opening of the hopper of the 4.00 m model. in addition, you benefit from a hopper that empties completely and properly as you progress through its V-bottom.
The standard hydraulic top link reduced overhang during transport and manoeuvres. In practice you have numerous benefits such as the higher clearance for headland turns and the possibility to lift the coulter bar in areas you wish to work without seeding.
