The machine can apply four layers of wrap in 18 seconds, and six layers of wrap in under 25 seconds.
Techagro is one of the largest agricultural fairs in Central Europe, attracting over 100,000 visitors. It featured nine winners of the Grand Prix Techagro 2016 awards for innovation.
Among them was LEMKEN’s automated calibration process for the Solitair 25, the first model of its new generation of Solitair pneumatic seed drills, which was launched at Agritechnica 2015.
Calibration and the seeding amount test can be performed from the tractor cab.
The operator only needs to enter core parameters such as thousand-grain weight, seeding rate and maximum working speed at the terminal.
Automated calibration makes drilling preparation more efficient and faster, and avoids errors.
For calibration, seeds are transported to a weighing unit in the seed hopper by a blower fan.
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 working speed, before starting the seeding process.
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.
Individually driven metering units allow the seeding rate to be modified by adjusting the motor speed and the stepless cell wheel, for optimum seed flow in any situation.
