Horsch has upgraded its well-regarded Maestro drill with new CV and RV models.
The Maestro CV can now use a central hopper for seed and fertiliser, known as Main Tank Supply, or a large fertiliser hopper and individual seed tanks as with the previous Maestro CC. There’s a simple, flexible mechanism to vary the number of rows and the spacing.
The capacity of the central tank in Main Tanks Supply configuration is 3,000 litres for fertiliser and 800 litres for seed. If the fertiliser-only central tank is used, the capacity is 3,000 litres with 70 litres of seed per row hopper. In addition to the eight- and 12-row versions, a new nine-row version is available.
The Maestro RV model is an eight-row mounted unit with one seed tank per row. Fertiliser supply is carried out via a front-mounted pressurised hopper, such as the HORSCH Partner 2000 FT.
AirVac metering system
The Maestro CV and RV are equipped with a completely new metering device, AirVac, that’s easy to adjust and offers high accuracy. The vacuum metering device works with a scraper that doesn’t need to be adjusted, requiring only the correct metering disc and reducing seed handling considerably.
This increases the range of the standard single grains that can be handled (maize, sugar beet, sunflower, soya and rape), with further varieties, such as beans and peas, possible in the future. The metering unit is still driven electrically to use technologies like SectionControl and VariableRate for every individual row.
The seed body has been revised for higher stability and a high hydraulic coulter pressure. It’s connected to the main frame with a new clamping profile that makes it easy to alter the number of rows from 12 to eight, a key requirement for customers.
The fertiliser is applied via a single-disc fertiliser coulter and its depth can be controlled separately, which is particularly helpful on heavy, sticky soils. The fertiliser coulter is attached to the row unit and the row spacings can be modified easily.
