The KUHN GMD 5251 TC center-pivot disc mower adds to the range of trailed GMD models with 17'1 of working width. With a center pivot, the mower is able to get all the hay to the left, right or anywhere in between for maximum productivity. This machine provides high work output and is perfectly adapted to medium-sized tractors. This model features the lubed-for-life Optidisc® cutterbar equipped with the Fast-Fit® quick knife attachment system. All discs are driven from the center of the cutterbar which simplifies drivelines and significantly reduces maintenance. The integrated narrow transport system allows for rapid transition from field to field and improved safety on the road.
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. These mowers come standard with the Fast-Fit® quick-release knife system. 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 Fast-Fit® quick-release knife system allows an operator to rapidly change out cutting knives with the use of a simple tool, yet still retain optimum cut quality and knife life. With Fast-Fit, an operator can achieve up to 50% time savings over a standard system.
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.
