Trailed Simplicity and VersatilityAs the first to market and industry leader, KUHN knows disc mowers. The GMD 51 TL Series trailed disc mowers have many of the same great features you have come to know and love. These trailed mowers offer high working rates, simple adjustments and low maintenance for dependable grass and forage harvesting. They provide easy tractor attachments, as well as improved contour following, compared to the fully mounted models. The trailed design also lowers the tractors ballast requirement, allowing use with smaller tractors while maintaining excellent stability in both work and transport.
Features may include:
Lubed-For-Life Optidisc® CutterbarThe Optidisc® cutterbar provides a flat, streamlined profile so that soil and crop residue do not accumulate and material flows smoothly, even in heavy, difficult crop conditions. Optidisc cutterbars are designed and tested with a zero oil change interval. The highly-polished gears and synthetic gear oil ensure that this system does not require any regular internal maintenance, eliminating the need for cutterbar oil changes throughout the life of the machine.
Differential Disc SpacingThe innovative design of the Optidisc cutterbar offers exclusive differential disc spacing.
Discs & Open ConesThe new style discs incorporate flat angled leading edges to lift the crop off of the cutterbar and promote fast movement of the crop through the machine to be laid in an even swath. On the underside of the disc, there are welded-on scrapers. These scrapers keep the cutterbar clean of mud, dirt and debris when mowing in wet or dusty conditions.
Similar to the discs, the open cones have large area leading edges to evacuate the crop being cut and push the crop towards the center of the machine leaving a desirable edge to the swath. The open cone design also makes them easier to clean for less machine vibration and easier access to bolts on the disc whenever maintenance needs to be performed.
Protectadrive® Disc Bearing StationsProtectadrive® Safety: Every minute saved during the hay season is precious. Ultimate protection, from the externally removable Protectadrive disc bearing stations, provides maximum reliability and quick service. In the event of an impact between a disc and an obstacle, the shaft holding the disc can shear just above the bearing. This is thanks to its carefully dimensioned shear groove. As a result, the gear teeth are protected.
Extra Rigidity Where it Counts: Disc bearing stations are attached by bolts that pass through the entire cutterbar. This is an exceptionally strong and secure attachment with no risk of mount being torn out of the cutterbar in case of shocks. The disc drive pinion is held precisely in place, all resulting in excellent reliability and reduced maintenance costs.
Gear-to-Gear Power Transmission: Gear-to-gear power transmission, a staple of all KUHN disc mowers, allows for maximum power to be transferred through all gears in the cutterbar. Unlike other gear cutterbars, equal sized gears throughout reduces torque on the gear teeth and leads to unsurpassed reliability and longevity.
