Overview
Kuhn GMD 50 TL Series
Trailed Simplicity and Versatility

With working widths ranging from 9’2” to 13’, these mowers offer high working rates, simple adjustments and low maintenance, for dependable grass and forage harvesting.

KUHN GMD 50 TL Series trailed disc mowers cut more acres per hour and offer simple adjustments, low maintenance, and dependable grass cutting. These trailed mowers provide easier tractor attachment, as well as cutterbar flotation and contour following, compared to fully-mounted models.

The trailed design also lowers the tractor ballast requirement, allowing use with smaller tractors, while maintaining excellent stability both at work and in transport. These mowers are the logical, practical alternative to mounted disc mower and “caddy” combinations.

The GMD TL models provide easy hook-and-go attachment that gets them in the field faster. The Optidisc® cutterbar, with differential disc spacing, ensures a clean cut, even in challenging conditions. This cutterbar is also “lubed for life”, decreasing overall maintenance requirements. Protectadrive® cutterbar protection provides unsurpassed reliability and these machines have improved suspension with greater adjustability. Get quality and reliability, along with outstanding support and maximum resale value, from the pioneer in disc mower technology and the world’s leading implement manufacturer.

Kuhn GMD 50 TL Series Plastic Rock Guards

A HDPE (high-density polyethylene) rock guard can be mounted on the underside of the front hood for added protection in rocky conditions.

Kuhn GMD 50 TL Series High-Lift Skids Shoes

For customers requiring a higher cut height for certain crops or when cutting in rocky conditions. The skids are adjustable for cutting between 2.1” – 6”.

Kuhn GMD 50 TL Series CV Secondary PTO Shaft

For flexibility to steer around obstacles in the field with the mowers’ hydraulic swing cylinder or to mow directly behind the tractor without PTO chatter, a secondary PTO shaft equipped with a constant velocity joint can be factory ordered or field installed.

The Optidisc® Cutterbar: A Clean and Consistent Cut

Kuhn GMD 50 TL Series Lubed-For-Life Optidisc® Cutterbar

The 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. 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.

Kuhn GMD 50 TL Series Differential Disc Spacing

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

1- 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.

2- More Distance for Easy Crop Passage: Wider spacing (2) 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.

Kuhn GMD 50 TL Series Discs

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.

Kuhn GMD 50 TL Series Protectadrive® Disc Bearing Stations

// 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. 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.

Exceptional Terrain Following

Kuhn GMD 50 TL Series 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.

Kuhn GMD 50 TL Series 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.

Kuhn GMD 50 TL Series 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.

Kuhn GMD 50 TL Series Hitch Options to Meet Your Needs

To best meet your needs, choose between a Cat 2/3N quick hitch compatible 2-point hitch and a simple drawbar hitch for your KUHN 50 TL Series mower.

The Cat. 2/3N quick-hitch compatible 2-point hitch provides a fully controlled connection and allows easy adjustment to maintain a level PTO. It also provides more ground clearance for previously mowed crops to pass through. Connecting arms pivot during hookup for easy alignment. All connecting hitches must meet current ASABE specifications.

The drawbar hitch is easy to hook up and the heavy-duty build provides dependability and long life. The built-in swivel allows movement in three dimensions to easily adapt to uneven field conditions.

Simple Design and Easy Service

Kuhn GMD 50 TL Series Direct Drive Design

The direct design provides easy access for servicing and fully eliminates belts. Reliability is greatly improved when working in longer, tough or lodged crops. Unlike competitive models that require daily greasing, the driveshaft to the cutterbar uses maintenance-free U-joints. These joints reduce overall maintenance and eliminate excessive wear from improper maintenance.

Kuhn GMD 50 TL Series 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.
