Kuhn has set a world record for raking with a GA 15131 gyrorake covering 188.9 hectares in only 8 hours.
The record just verified by the DLG, was achieved on August 26, 2019 in Braedstrup, Denmark with a four rotor gyrorake GA 15131, standard model. It was hitched to a John Deere 6250R tractor in the presence of the German institute DLG – Deutsche Landwirtschafts Gesellschaft.
The DLG Institute confirmed, “188.9 hectares were raked in 8 hours, which represents an average of 23.6 hectares per hour.”
The Kuhn’s GA 15131 gyrorake offers a working width of 9.5 to 14.7m.
Its 100 per cent hydraulic drive allows adaptation of the rotor speed to the forage type and yield while minimising maintenance tasks.
A Boost function increases the speed of the front rotors by 20 per cent compared to the rear ones in order to form a homogeneous and airy windrow.
The individual rotor lift allowed the operator to achieve the world record by avoiding obstacles despite the varying paddock shapes.
The operator also appreciated both the CCI 1200 ISOBUS terminal allowing him to visualise the work performed and to optimise the rotor adjustment without any downtime, as well as the ease of use of the WTK joystick.
A dairy farm in the hilly central Jutland region of Denmark was chosen to set the record.
Mikael Skeldal, who runs the farm with his two brothers and sister, drove the John Deere 6250R tractor equipped with AutoTrac guidance system, the intuitive Gen4 CommandCenter and the ergonomic CommandPRO joystick.
The representative from the DLG institute who certified the record, carried out several measurements on the spot.
The time and surface were precisely determined, and the quality of the work was measured by various samples collected, confirming the good forage quality.
The windrow profile, losses and forage characteristics have been identified and qualified in a technical report to be published shortly by the DLG Institute.
