AIRVAC AND AIRSPEED – VERSATILE – Precise – EFFICIENT

The design of the new metering device generation AirVac and AirSpeed is basically similar. The metering devices work according to the same metering principle. They can be used universally for an exact grain singulation. Due to different metering discs, maize, sunflowers, sugarbeet, soybeans, sorghum and rape can be singulated reliably.
The AirVac system is based on the principle of vacuum singulation where the seed is sucked to a perforated disc. The AirSpeed system works according to the overpressure principle where the grains are pressed to the perforated disc. In both metering devices the grains pass through a singulator that sees to it that duplicates are removed. The special feature of the component is that it does not have to be changed if the crop is changed and that the user does not have to carry out any adjustment works. The contour of the singulator has been optimised in such a way that a reliable singulation for all crops is guaranteed.
The basic difference of the two new metering device generations is the transfer of the seed from the metering device into the soil: After the singulation the AirVac systems leads the seed via a fall tube to the bottom of the furrow and the seed is pressed down by the catching roller if necessary. With the AirSpeed system the singulated grains are seized by an air current, accelerated and shot with the air current through the shoot pipe into the soil. They are caught and embedded by the installed catching roller.
In both metering devices the grains pass a grain sensor in the fall resp. shoot pipe to guarantee an optimum monitoring of the seeding success. The measuring technology of the sensor is able to count the grains, to determine the spacings between the grains and thus also to transmit an information to the driver with regard to double spots or gaps.
The transmitted values of the singulation accuracy are displayed clearly at the terminal of the machine and additionally increase safety while sowing.
The new metering device generations AirVac and AirSpeed are driven electrically as a standard and each row can be controlled individually. This technology co-operates with the well-proven functions single row switch-off, SectionControl, VariableRate and tramline control.
For VariableRate the metering systems are designed in such a way that the seed rate can be modified for every single row. With the tramline control it is possible to individually adapt the seed rate in the row at the left and the right side of the tramline. With these advanced functions all measures to increase precising while sowing can be used to full capacity.

The Compact Mid-Size Machine

The compact Maestro CV / CX unit that consists of a highcapacity seed wagon and a seed bar for a working width of up to 7.2 m provides high efficiency whereas the demands on the tractor are comparatively low.
To meet the requirements of the customers in an optimum way, two configurations of the seed wagon of the Maestro CV / CX are available:

Single hopper for fertiliser

The hopper with a capacity of 3 000 liter is used for applying fertiliser via the coulters of the underground fertilisation system. In this case, the seed is supplied in the large single row boxes with a capacity of 70 liter.

Double hopper for fertiliser and seed

The new double hopper system MTS (Main Tank Supply) for the Maestro CV has a capacity of 3 000 litres for fertiliser and 800 litres for seed. By means of the MTS technology the seed is continuously transported to the individual row units and singulated by the AirVac metering device. The major advantage of MTS is the simple filling of the central seed hopper with the simultaneous singulation of the seed in the row with a short distance to the seed furrow.
The fertiliser hopper of both versions is equipped with the well-proven HORSCH metering technology and can reliably and precisely feed the underground fertilisation system of the Maestro.
The coulter attachment of the Maestro can be equipped with 8 rows and 9 rows with a row spacing of 70 / 70 / 80 cm and 30“. When used with 12 rows, row spacings of 45 and 50 cm are available. The newly developed clamping profile allows for a simple retrofitting from 12 to 8 rows.
The new row body is equipped with a wide, stable parallelogram and a hydraulic cylinder to generate the coulter pressure is standard equipment. Coulter pressures up to 350 kg per row can be used manually at the terminal or fully automatically with the innovative coulter pressure regulation system AutoForce. The weight of the seed wagon is used to generate the coulter pressure on the whole width of the machine and guarantees a relief of the seed wagon tyres while sowing.

Features

Press wheels

for a better embedding of the grains

Which press wheel is suitable for which use?

  • The finger wheel is ideal for heavy soils.
  • The spike wheel is ideal for lighter sites.
  • The rubber closing wheels are ideal for light sandy sites.
  • If the furrow wall gets compacted because of the double disc seed coulters, it is broken by the finger / spike wheel – the furrow is removed.
  • Seed furrow is not opened after sowing under dry conditions, especially on heavy clayey sites
  • Development of the maize root is encouraged
  • There is one finger / spike wheel and one standard wheel per row to control the depth and to avoid moving the grains.
  • However, the wheels are not suitable for shallow sowing.
