HORSCH presents a new technology for the Maestro SW single grain seed drills

ContourFarming - automatic adaption of the metering revolutions over the working width of the machine when cornering
  • For crops like maize, sunflowers and sugar beet the optimum seed size or the desired population density is indicated by the breeder based on variety and site. These specifications mostly are based on tests. Every variety has certain tolerance range, e. g. from 60,000 to 75,000 plants per hectare. The seed quantity should also be in this range, even on the headlands and even when cornering. The HORSCH Maestro line with its individually electrically driven metering units is the ideal basis for the integrating of an automatic adaption of the seed quantity when cornering. The equipment option ContourFarming for the Maestro 16, 24 and 36 SW also includes two additional radar sensors for speed detection. The standard radar sensor is in the middle of the machine. The two additional radar sensors are mounted at the end of each wing section of the single grain seed drill and records the speed. If the machines drives into a corner, the inner radar sensor registers a lower speed and the outer one a higher speed. If the difference is more than 0.6 km/h, every single row motor of the metering devices is supplied – automatically based on fixed control curve – with a value that has been corrected in relation to the speed change.
  • As a result, measured by the time unit, the machine places less seed in the inside rows and more seed in the outside area. Thus, the seed quantity per hectare remains constant over the whole working width of the machine. This process runs automatically and allows for making optimum use of the yield potential of the respective plant.
  • WITH ContourFarming: The seed quantity per row does not change when turning.
    WITH ContourFarming:
    The seed quantity per row (90.000 grains/ha) does NOT change when turning.
  • WITHOUT ContourFarming: The seed quantity is higher in the bend (X+90.000 grains/ha) – on the outside it is lower  (X-90.000 grains/ha)
    WITHOUT ContourFarming:
    The seed quantity is higher in the bend (X+90.000 grains/ha) – on the outside it is lower (X-90.000 grains/ha)
