For the ZA-M with mechanical spreading disc drive, there is the Control package with AmaDos+ for electronic control of the spread rate, independent of the forward speed.

Benefits from AmaDos+:

  • The preselected spread rate always remains the same whatever the optimum working speed selected. This is particularly beneficial with tractors with a variable transmission
  • Changes to the rate can be made to either both sides or just one in freely selectable steps with this modern operating terminal. This reduces costs and protects the environment
  • Robust actuator motors on the rate shutters adjust the spread rate
  • The hydraulic shutters in the double shutter control system are actuated independently of the electronic metering shutters. This is quicker and reduces the workload of the electronic actuators
  • All electronic components are protected from water ingress and corrosion
  • The speed is recorded using a drive shaft sensor or the tractor signal socket
  • Simple calibration programe with independent rate setting determination
  • Robust sensor technology for function monitoring e.g. of the shutter position
  • Can be extended to other applications, e.g. as a hectare counter during manure spreading, cultivation or mowing with a separate working position sensor
  • Serial interface available for documentation and the connection of N-sensors and GPS-terminal supplied application maps for site-specific fertilisation
  • Job memory for up to 20 field records
