Following the success in 2014 of individual Seletron nozzle section switching, Landquip will offer for 2015 the twin or quad multi auto nozzle system. The operator simply programmes the ideal nozzles to achieve the required spray quality over a range of flow rates and forward speeds.
This automatic nozzle-by-nozzle control can be used to stay within the LERAP working pressures around headland water courses or to maintain a fine to medium spray as required for small target, e.g. blackgrass, etc.
The system is also ideally suited to high volume fertiliser application by automatically switching from one jet to another for headland turns. Whilst the controller will automatically maintain application rate, the pressure drop when slowing down to negotiate a headland turn will change the quality and distribution and may well move outside the nozzles' operating range. By equipping the nozzle cluster with more than one Umbrella jet the auto nozzle-by-nozzle control will select the smaller jet for headland turns moving back to the larger jet once speed has been regained in the field, thereby maintaining application quality and distribution/pattern throughout the field whilst avoiding scorch from too high working pressures.
