After the success of the GPS-Switch system on fertiliser spreaders and sprayers, sowing now is the focus for the use of this technology. The switching on and off of the electric metering system is controlled via GPS. In this way, the stress on the driver is reduced and an improvement in the operational performance is achieved especially in small fields with many headland turns.
GPS-Switch controls, dependent on the position of the seed drill and the adjustments by the driver, the switch-on and off points of the electric metering unit of the AD-P or Avant. On the Avant (see page 34), a 3 m half-side switching is possible.
In this way, during practical operation, the often found over or under sown areas in critical spots, such as on the headland or in wedges can be minimised. Sowing ‘gaps’ are now things of the past! The driver can fully concentrate on driving and can operate the drill independently to achieve a neat transition.
Saving seed and higher work rates: with GPS-Switch now applicable to sowing, the classic method of raising the drill to switch it off which leaves some seed on the surface and gives more chances of misses is avoided so that the sown seed is better placed. For a better optimisation of the switch-on and switch-off points, AMAZONE recommends RTK accuracy.
The future today: in addition, becoming increasingly popular is the use of sowing maps, where the seed rates can be matched to individual zones in the field – such as hills and hollows or changes in soil type. Task Controller is available as a special option. The AMATRON 3 terminal (per ISO-XML) or GPS-Maps allows the simple realisation of seed maps. Standardised file formats can be imported into the system which is then implemented fully automatically. A graphic display of the map in the background offers a good overview.
