Variable working width of between 8.40m and 12.50m makes the GA 13131 Gyrorake the biggest tool in the KUHN rake range today.
The headstock linked to the frame has a hydraulic unit, so machine drive is always in line, even in tight bends. Each rotor is driven hydraulically, so the constraint of greasing numerous transmissions is removed.
According to forage type and density, front rotor rotation speed can be accelerated from the tractor cab in order to enhance windrow formation. This function is greatly appreciated, by drivers of pick-up machines following the raking operation, for the regular, airy windrows that are produced.
All functions concerning folding / unfolding, windrow width adjustment, working width, raking height, plot management… are managed from the cab via the integrated VT50 terminal.
Manoeuvre sequencing is also programmable and provides a high degree of operating comfort for U-turns on headlands. To finish the plot, the rotors can be lifted individually or simultaneously.
Switching between transport and work position requires no arm or guard manipulation, and road height remains under 4m.
3D rotor suspension mount and wheels closely positioned to the tines make for excellent ground following. The exclusive STABILIFT system, that locks the rotors in position for windrow clearance and transport, as well as the pivoting wheels, contribute to the protection of plant cover on headlands and on bends.
Operating comfort can be increased even further with the camera and LED headlights that are available as an option.
