2025 Kuhn GMD 25 F Series 3125 F

KUHN GMD 25 F Series front mounted mowers, with working widths ranging from 10’2” to 11’6 can be used on their own, or as part of a triple-mower combination allowing you to cut up to 32’6” in one pass.

KUHN is the reference in the front mount mower market with the GMD 25 F Series front mounted disc mowers. These mowers feature an attractive, functionally designed headstock that offers exceptional terrain following, flexible enough to adapt to any terrain changes encountered in the field. The compact frame, shaped like a hammerhead shark, offers improved visibility for the operator. These machines feature the heavy-duty Optidisc® Elite cutterbar utilizing a through-bolted design and lubed-for life technology, which guarantees minimal maintenance and maximized cutting efficiency. Protectadrive® safety provides maximum reliability and quick service, and the Fast-Fit® knife system allows you to quickly change out the knives with the use of a simple tool. For even greater mowing efficiency, combine a GMD 25 F Series front mount mower with one of KUHN’s GMD 30 Series rear mounted mowers.

Features may include:

A Clean and Consistent Cut

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.

• Less Distance for a Clean Cut: Narrower spacing at diverging discs provides greater knife overlap, which results in a clean cut, even when the grass is short or light.

• More Distance for Easy Crop Passage: Wider spacing at converging discs provides more space for the crop to pass. Cut crop is quickly carried away from the cutting area, greatly improving the cut quality.

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 converging drums work together with the OptiDisc® Elite cutterbar to create smooth swaths, narrow enough to fit between the tractor tires to avoid value robbing run-over of the cut crop. Drums are powered via shafts to ensure full power in all mowing conditions.

• Protectadrive® 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.
