Kuhn unveils 14.5m mower for high HP harvesters
With most forage harvester manufacturers offering machines touching 1000hp, the logistics puzzle has always been ‘dropping” grass and pulling into a swath big enough to feed the “beast”.
Simple and practical to use, the machines offer working widths from 7.7 to 9.3 metres, making them suitable for contractors or medium and large farms wishing to increase throughput of round or large square balers and forage harvesters.
Offering the ability to deliver adjustable swath widths from 1.4 to 2.3m, the GA 9531+ model uses 15 tine arms on its 4m diameter rotors, offering the ability to group two windrows of grass, or the straw from behind combine harvesters equipped with cutting widths of up to 7.5m.
Utilising well-proven features from the extensive Gyrorake range, the rotor drive features a double reduction via the Master Drive GIII gearbox, which has proven record of robustness in all conditions.
The GA 9531+ model features six wheels per rotor, incorporating a tandem axle) for superior ground following on all types of terrain, working in conjunction with 3-D articulation, alongside increased stability at higher speeds.
Designed to offer simple adjustment of the working or windrow width and the raking height (the latter can be done hydraulically) the Stabilift system locks the rotors in the windrow clearance phase, maximising ground clearance during headland turns. It also helps maintain a low centre of gravity and increased stability, particularly on slopes, while also locking the rotors during transport for increased safety.
