The DP 44 models incorporate the following regulation elements:
Dosage in kg/ha. We can choose from several systems:
Constant flow. A millimetric index indicates the position of the opening of the product outlet windows from the hopper to the spreading discs. Our working speed should be constant. The opening/closing of the passage of fertiliser is made by a hydraulic on/off system.
A variant of this system is that of electrical control via the cab console. Manually, but without stopping the progress of the tractor, we can increase the of fertiliser drop flow and, therefore, the kg/ha.
Flow proportional to the speed. By means of electronic positioning control of the electric actuators that open and close the passage of fertiliser to the discs. This allows us to vary the working speed while maintaining the kg/ha desired.
The APOLLO device is continuously weighing, via four load cells that measure the actual weight of the assembly. No prior calibration testing is required.
Working width. To adapt to any need of the farmer based on the type of land farmed. This is done very simply with the help of the Instruction Manual. Adjustable from 12 to 44 m for the majority of fertilisers and maintaining a coefficient of variation below 10% as required by the European standards.
