Kuhn rake GA 15131, a record-breaking machine

Just under 190 hectares worked in 8 hours, with an average hourly rate of 23.6 hectares. This is the new windrowing world record, certified by the German DLG institute (Deutsche Landwirtschafts Gesellschaft - German Agricultural Society). The rake Kuhn GA 15131, a four-rotor model combined for the occasion with a John Deere 6250R tractor, established it last August on a farm in the Danish city of Braedstrup. The DLG official, who validated the record, made several surveys on the spot.

The time and surface were determined precisely, while the quality of the work was measured by collecting various samples. The profile of the swath, the losses and the characteristics of the forage were quantified and defined in a scientific report that will be published by DLG. Presented in Braedstrup in its standard configuration, the GA 15131 model, available with working widths from a minimum of 9.5 to a maximum of 14.7 metres, has been studied down to the smallest detail to offer top level performance.

All confirmed by this world record, made possible by a constructive architecture designed for excellent performance. The hydraulic transmission, for example, makes it possible to adapt the rotors to the type of forage and to the volume to be handled - explains the manufacturer with a technical note - so that field operations are even more efficient, limiting maintenance requirements to a minimum.

The windrows are also 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 regular and airy swath.

Another strength of the GA 15131 rotary rakes is the option for the user to lift each rotor separately to avoid any obstacles on the ground.
