Trailed Simplicity and Versatility

With working widths ranging from 8’10” to 13’, KUHN GMD 51 TL Series mowers get you in and out of the field faster.

As 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® Elite Cutterbar
  • 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. 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.
Differential Disc Spacing
  • The innovative design of the Optidisc Elite cutterbar offers exclusive differential disc spacing.
Discs & Open Cones
  • The 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
Pro-Active Lift®
  • This maintenance-free system allows the machine to quickly adapt to abrupt changes in terrain or when an obstruction is encountered in the field. The cutting head is able to move up and back simultaneously, dissipating the force of any impact and providing space to clear the obstacle. This unique design reduces scalping to preserve crop stubble and helps protect the machine from potential damage. A slotted linkage on each side provide guidance for the header and eliminates the need to run the hydraulics in the float position.
Constant Float Suspension
  • 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.
Superior Maneuverability
  • 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.
Convenient Height Adjustment
  • 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.
Steel Side Sheets
  • The steel side sheets provide a definitive line between cut and uncut crop. This makes the subsequent pass easier to follow for the operator and also gives the machine a finished look.
