Always concerned with increasing the farmers efficiency, Kverneland presents a new combination of seeder integrated on compact disc and cultivators. The seeding operations are made in one pass at the same time as stubbling or seedbed preparation, with accuracy over the full working width.
The a-drill has been designed to conform with the nitrate directives adopted in 1991 by the EU. One of the measures taken results in the need for the soil to be covered in the autumn by vegetation, which will absorb nitrogen from the soil and air and convert it into organic nitrogen. Kverneland has two a-drill models differentiated by 2 hopper capacities: 200 and 500 liters.
The Kverneland compact disc & cultivators can have both models depending of the type of seed (size), the seed rate /ha, the working speed and the working width. The a-drill 200 ltr has a plastic hopper and the a-drill 500 ltr has a steel hopper.
a-drills are able to seed all types of seeds and even a mix of different seeds. 2 rotors are delivered as standard for matching the different seed size and rate. They will spread the seeds through 8 dispersion plates. For big seeds like horse beans or peas, Kverneland proposes the Flex rotor.
2 fans are available according to the machine type and the seed rate/ha. Trailed machines have the hydraulic fan whilst the mounted machine can have either electric or hydraulic fan drive. Hydraulic fan drive is strongly recommended when the seed rate is important, especially with high working speed (up to 14 kg/min – 100 kg/ha with 7m at 12 km/h). For seed rate below 4 kg/min (50kg/min with 4m machine at 12km/h), the electric fan is enough to carry the seeds properly.
All models can have 2 different control boxes: the control box 3.2 has all the basic operations (rotor speed with fix rate, calibration test, fan ON/OFF). The control box 5.2, on top of the basic functions, also has speed regulation, headlands stops, ha and speed counter, emptying function, etc…
Kverneland paid great attention to the safety for filling operations. That’s the reason why all machines are equipped with 2 safety guards and anti-slipping steps. All operations can be done safely!
