Maestro CV

HORSCH modernises the Maestro family with the CV and RV line

The highlight of the new Maestro CV is the possibility to use a central hopper for seed and fertiliser or, as before, a large fertiliser hopper and individual seed tanks. With regard to the fixing of the seed units spacing, HORSCH opted for a flexible solution to be able to vary the number of rows and the spacing.

Finally, the machine is equipped with a completely new metering device that can easily be adjusted and that works with the usual high accuracy.

The seed body itself is revised. The focus was on the highest stability and a high hydraulic coulter pressure that has proven its worth before. It is connected to the main frame with a clamping profile to be able to alter the number of rows in an easy and uncomplicated way from 12 to 8 – which was a central requirement from the customers. The fertiliser is applied via a single disc fertiliser coulter the depth of which can be controlled separately and which, among others, has its advantages on heavy, sticky soils. The fertiliser coulter is attached to the row unit and thus the row spacings can be modified easily.

All other features – like the variability of the press wheels – are kept.

For the Maestro RV and RX the well-proven principle of one seed tank per row was maintained. The fertiliser supply is carried out via a pressurised hopper, e.g. the HORSCH Partner 2000 FT.

Maestro RV

This is the central difference to the Maestro CV and CX. It, too, is available with one seed tank per row, but now also, as known from the large Maestro SW, with a central tank for fertiliser and seed. This technology is called MTS - Main Tank Supply. The capacity of the central tank is 3,000 l for fertiliser and 800 l for seed. If the central tank is used for fertilizer only, the capacity amounts to 3,000 l and 70 l of seed per row. In addition to the 8- and 12- row version, the Maestro CV is also available as a 9-row version.

The CV and RV series differ from the CX and RX series in the metering device. CV and RV are equipped with a metering device called AirVac. The vacuum metering device that is a completely new development works with a scraper, that don’t has to be adjusted. You only have to choose the corresponding metering disc which reduces the handling considerably. It also allows increase the range of the standard single grain range can handle (maize, sugar beet, sunflower, soya and rape). In the future, the metering of further crops, for example varieties of beans and peas, will be possible. This guarantees enormous flexibility. The AirVac metering device is particularly suitable for sensitive seeds such as sunflower. In sticky or moist soils, it still ensures optimum seed placement because it can also be sown without a trapping roller. 

Maestro RX

The metering unit is still driven electrically to be able to use technologies like SectionControl and VariableRate for every individual row as usual.

The CX and RX series are equipped with the so-called AirSpeed metering unit, which operates with overpressure. The scraper does not have to be adjusted separately on this metering unit either. With the overpressure metering unit, the grains are not placed in free fall in the ground, but shot into the ground with the support of compressed air. The grain is slowed down with a catch roller and securely fixed in the soil. One advantage of the AirSpeed dosing unit is that it can work at speeds of up to 16 km/h. This is only one of the reasons why it is well adapted to the conditions in Europe.
