2025 Kuhn GMD 51 TC Series 5251 TC

With 17’1” of cutting width, the KUHN GMD 5251 TC proves to be a worthwhile investment for any large farm or custom operation looking to increase profitability by doing more work in less time.

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® Elite 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:

• The Optidisc® Elite 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 Elite 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.

• The 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.

• The header is suspended on each side by a long, large-diameter spring that provides a constant range of flotation. The floating head lifts up and back, and can oscillate from side-to-side, to closely follow the ground contours and conform to irregular terrain. This reduces the amount of missed crop in the field and helps keep dirt out of the harvested crop.

• The heavy-duty Gyrodine® gearbox is designed to withstand the most severe pull-through force from the hitch to the machine. The swivel design allows in excess of a 90° turn while keeping the PTO driveline straight. This design also allows extremely tight turns for clean, square corners while minimizing PTO vibration and wear. Choose a drawbar swivel hitch or a 2-point attachment on the 51 TC Series disc mowers. Side guards on the drawbar hitch protect the body if contacted by the tractor tire in a very tight turn. This reduces the chance of costly repairs and helps maintain the appearance of the machine.

• A built-in lengthways transport position allows operators to quickly go from field to field and reduces risks of accidents, or operator’s fatigue if traveling long distances. Wheels in forward position allow for an excellent center of balance, with easy entry into fields having narrow gateways.

• The height change adjustments are fast and simple, and do not require tools. Cutting height is set using a special turnbuckle that adjusts easily with only modest effort. A convenient gauge on the turnbuckle shows the cutting height for precise field adjustments.
