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”.
Kuhn has announced an expansion of its range of disc mowers, distributed by Norwood in New Zealand, with the addition of two new vertically folding rear mounted models, the GMD 3515 and GMD 4015.
Offering working widths of 3.50 and 3.95 metres respectively, the units are designed for farms strongly focused on forage production.
“When combined with a front mower, the GMD 1015 series machines will help increase work outputs,” says Peter Manderson, New Zealand Brand Manager for KUHN.
The 125° vertical folding geometry ensures a centre of gravity centred behind the tractor during transport, while also helping to reduce overall dimensions and rear overhang. The configuration is said to provide improved safety during transport, especially when hitched in combination with a front mower.
The mowing unit is suspended from the chassis at its centre, allowing efficient ground following, especially in rolling or hilly terrain, while at the headland, the unit is raised hydraulically, offering clearance of at least 350mm under the first disc for passing over the swath. Hydraulic ground pressure adjustment helps reduce cutter-bar ground pressure which in turn reduces sward damage, particularly when operating in poor soil conditions.
The Lift-Control system combines this hydraulic ground pressure reduction with a Non- Stop safety feature, that in the event of encountering an obstacle, the mowing unit shifts rearwards, resulting in reduced ground pressure that allows the mower to clear the obstacle. Once the obstacle has been passed, the machine automatically repositions itself to the working position.
These two models are equipped with the wellknown, maintenance-free, OptiDisc Elite cutter-bar, said to offer robustness and cutting quality in all conditions, with the additional benefit of the Fast-Fit, rapid knife attachment system. Both models are available to order now, with delivery for the upcoming 2025/2026 season.
