The future of pneumaticsingle grain seed technology.

Fast – precise – versatile.

The Maestro – a master of singulation

Due to its exact grain singulation it is universally suitable for maize, soy, sunflowers and sugarbeet. The patented Maestro single grain technology particularly excels due to three features:

  • The unique metering system
  • The extremely small single grain metering unit
  • The placement quality control.

The metering system is based on a completely new metering disc. It does not have the usual holes, but grooves that open up to the outside. Thus, together with the new scraper, the singulation results achieved in a large frequency range from 0 to 30 Hz are excellent. 30 Hz correspond to a working speed of 12 km/h for the usual 90 000 grains of maize per hectare.
The crucial factor for these results is the smooth transition of the grains from a circular to a linear movement in the placement area. There are no disturbing centrifugal forces in the fall sluice. This extraordinary accuracy is undependend from the rotational frequency of the metering disc and is exactly controlled by sensors. As the grains are not shot into the soil pneumatically, it is possible to work without a catching roller at the seed unit, e. g. under wet conditions.
The software in the Horsch Terminal is set up in such a way that the driver can clearly see the exact missing and double spots as well as the variation coefficient for every single row. Thus, the driver can respond any time to the most different conditions like seed or seedbed quality and use the machine to its full capacity. The working speed can thus be adapted to the individual requirements for placement accuracy.

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.
