2020 Kuhn North America GMD Select Series 24

KUHN GMD Select Series mowers, with working widths of 5’3” to 9’2”, combine a simple structure with key features, resulting in a clean and even cut.

KUHN GMD Select Series disc mowers are an evolution of our economical machines for small and mid-sized farms. These simple, but durable, mowers offer fast, clean mowing of heavy grasses and delicate forage crops. They incorporate the proven 100 Series cutterbar that has decades of reliable service. As with all current KUHN mowers, Protectadrive® disc shear protection comes standard. A redesigned headstock keeps the mower close to the tractor, reducing overhang and increasing safety when mowing in rough fields. A standard outside swath wheel provides better definition between cut and uncut crop versus swath shields used on competitive machines. Multiple options allow the machine to be adapted to every customers’ particular needs.

Proven 100 Series Cutterbar

• Withstands the highest loads: special high-capacity bearings fitted in a one-piece sealed housing are not subject to distortion.

• Increased service life: disc pinion shaft bearings endure radial forces for maximum bearing life. This optimum position improves the load balance.

• Protection should an obstacle be struck: the Protectadrive® system is designed to protect the cutterbar gear train and minimizes the risk of downtime.

• High-wear resistance: knife attachment hardware is fully protected. For added safety, heat-treated steel cups are welded to the disc.

• Minimum wear or distortion risks: idler gear fasteners are located in heat treated steel cups. Correct alignment is ensured without the risk of distortion.

• Long-term reliability: large-diameter gearwheels in high-tensile forged steel with reinforced teeth.

• Perfect sealing: top-quality o-rings used on cutterbar bearing housings for a perfect, leak-free seal.

Standard discs allow for clean cutting and quick crop evacuation. Beveled reversible knives are standard. Ribbed knives are available for rocky conditions.

The shape of the discs allows for a quick transfer of crop rearward, allowing the crop to quickly be formed into a swath. A recut of the grass is therefore avoided. As crop leaves the cutting area, no outside support greatly reduces the chance of crop wrapping.

The swath wheel is mounted behind the outer cone and functions to separate cut crop from uncut crop allowing the right tractor wheels to drive over the ground instead of previously cut crop. Advantages of the swath wheel include it fitting entirely under the curtain, not being in contact with the ground and eliminating damage when backing or turning sharply.
