KUHN sets first world raking record
Four-rotor gyrorake did 188.9 hectares in eight hoursKUHN has successfully entered the record books with its GA 15131 four-rotor gyrorake raking over 180 hectares in eight hours hitched to a John Deere 6250R tractor.
The world record was set and certified by German agricultural institute, DLG, in August 2019 on a dairy farm in the hilly Central Jutland region of Denmark.
The DLG Institute confirmed: "188.9 hectares were raked in eight hours, which represents an average of 23.6 hectares per hour."
KUHN's GA 15131 gyrorake offers a working width of 9.5 to 14.7m and features a 100 per cent hydraulic drive that KUHN said allows perfect adaptation of the rotor speed to the forage type and yield whilst minimising maintenance tasks.
A BOOST function increased the speed of the front rotors by 20 per cent compared to the rear ones to form a homogeneous and airy windrow.
The individual rotor lift allowed the driver to avoid obstacles and achieve a consistent rake despite the varying paddock shapes. The CCI 1200 ISOBUS terminal allowed the driver to visualise the work performed and to optimise the rotor adjustment without downtime.
Mikael Skeldal, who runs the farm in Denmark with his two brothers and sister, drove the John Deere 6250R tractor equipped with AutoTrac guidance system, the Gen4 CommandCenter and the CommandPRO joystick.
A representative from the DLG institute carried out several measurements on the day including time, surface and quality of work which was determined using samples.
The windrow profile, losses and forage characteristics have been identified and qualified in a technical report to be published shortly by the DLG Institute.
