2024 Kuhn GMD 30 Series 8730

KUHN GMD 30 Series rear mounted mowers deliver a clean cut with a wide cutting width and are ideal for large-acreage producers. When paired with a GMD 25 front mount mower, they feature a total combined working width of up to 32’6”, taking productivity to a whole new level.

KUHN GMD 30 Series rear mounted mowers deliver a clean cut with a wide cutting width and are ideal for large-acreage producers. These mowers provide high reliability and quick cutting to help produce quality forage at a high output. The high-lift discs and Lift-Control® hydropneumatic suspension ensure excellent cut quality and crop throughput, even in the toughest conditions. Fast-Fit® knives and the Optidisc® Elite lubed-for-life cutterbar take the time and headache out of regular maintenance. Should the mower strike an obstacle while working, the continuous hydraulic safety automatically pivots up and back, minimizing the risk of damage. At the end of the season, store your KUHN GMD mower without any problems thanks to the vertical storage position of the machine.

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 innovative design of the Optidisc Elite cutterbar offers exclusive differential disc spacing.

• 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.

• Lift-Control is much more than just a suspension system with a nitrogen accumulator replacing the traditional spring. The main advantage of the Lift-Control system is derived from the exclusive way in which kinetic forces that act on the cutterbar are utilized. KUHN engineers have succeeded in making a dynamic suspension system, as opposed to the passive system most commonly used.

• For a clean cut on slopes and bends, the overlap between the front and rear units can be adjusted hydraulically between 12” and 18” (depending on the model combination) – even while driving. This is a real benefit for tractors with wide wheel spacing or large wheels.

• The possibility of lifting both rear mowing units individually via hydraulic cylinders is a big advantage on wedge-shaped fields and permits quick and easy maneuvers. This can be done directly from the cab. At the same time the system ensures a reduced ground pressure: beneficial to plant regrowth, cutterbar wear and power requirements.

• No farmer can afford to damage his mower during the peak of the season because of an unnoticed obstacle or maneuvering error. On the new rear units, the mowing unit pivots rearward around the bracing pin when hitting and obstacle. In this moment, oil is transferred toward the suspension cylinder. The resulting pressure increase facilitates the mowing unit raising to clear the obstruction. Return to the initial working position is carried out nonstop.
