Intended for use on medium and large farms, the latest Kuhn GA 7631 and GA 8131 semi-mounted central-delivery rakes come with working widths from 6.7m to 7.5m and 7.1m to 8m respectively.
The GA 13031 has a working width adjustable between 8.4 and 12.5metres.
It features a 100% hydraulic rotor drive, which is said to be exclusive in the KUHN range.
The design reduces maintenance by removing the need for daily greasing of secondary drive shafts, typically found in mechanical drive trains.
Master Drive GIII rotors are configured to achieve 3-D rotor articulation. With suspension springs on the front rotors and support wheels close to the tines, this allows the four rotors to provide excellent ground contour following.
This ensures minimal amounts of dirt or stones are drawn into the windrow, preserving the quality of the crop, while also reducing sward damage.
Unlike the larger GA 13131, which is controlled via an ISOBUS terminal, all folding/unfolding, working and windrow width adjustments are made with the tractor’s rear remote valves.
This makes for simple and cost-effective operation.
With a transport width of 3 metres and a sub 4m transport height, road travel is achieved without the need to remove any rotor arms.
