KUHN achieved the first raking world record on August 26, 2019 in Braedstrup, Denmark with the four rotor gyrorake GA 15131, a standard machine, 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.”
Synonymous with high capacity, versatility and impeccable quality of work, KUHN’s GA 15131 gyrorake offering a working width of 9.50 to 14.70 m is the basis of an ultra-high-performance harvesting chain.
Its exclusive 100% hydraulic drive allows perfect adaptation of the rotor speed to the forage type and yield whilst minimising maintenance tasks. The windrows are of very high quality thanks to the BOOST function, which increases the speed of the front rotors by 20% compared to the rear ones in order to form a homogeneous and airy windrow.
The individual rotor lift allowed the driver to achieve this performance by avoiding obstacles despite the varying paddock shapes. The driver 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.
