Lemken has developed an automated calibration process for its Solitair 25 drill that can be easily launched from the tractor cabin by the operator. They only need to enter core parameters such as thousand-grain weight, seeding rate and maximum working speed at the terminal; the control system then runs the full calibration process automatically as soon as it has been activated.
The calibration process is started by the newly developed vertically arranged metering units. Seeds are transported to a weighing unit in the machine’s seed hopper by a blower fan via a seed turnout. When the calibration sample has been weighed the results are transmitted to the job computer. The weigher automatically discharges the seed sample into the hopper. After that, the operator only needs to confirm the weighed result and the possible working speed before starting the seeding process.
The metering units, which are individually driven by an integrated electric motor, allow the seeding rate to be variably modified by adjusting the motor speed and the stepless cell wheel. This ensures that an optimum seed flow is maintained in any situation.
The automated calibration process makes drilling preparation more efficient and faster and avoids errors. The adjusted seed quantity can be easily checked with another calibration process. A more detailed calibration or check can be performed by calibrating individual width sections via their respective metering units.
