KUHN GF 1003 Series mounted rotary tedders, with working widths of 25’7” to 35’5”, are ideal for both custom operators and hay producers looking to shorten drying time of their crop. These machines provide exceptional tedding quality, resulting in a crop that is fully tedded over the entire width, and is efficiently and uniformly spread to maximize drying. Reduced drying times result in higher quality and nutritional value in hay and haylage.

The OptiTedd rotors are the secret to rapid drying, excellent ground following and low incorporation of impurities in the crop, helping maintain maximum forage quality. The exclusive DigiDrive® coupling system provides low maintenance, long life and increased safety. These machines feature KUHN’s Headland Lift Control system, making them easy to lift and maneuver on headlands, while limiting the introduction of foreign materials like dust into the forage. Despite the wide dimensions at work, these machines are incredibly compact in transport. Their 9’10” transport width is a considerable asset when accessing the narrowest fields and also provides safety and comfort during over-the-road travel.

Your benefits

Fast and Uniform Crop Drying and Distribution

GF_HighQualityTines.jpg

High-Quality Tines

When it comes to tines that actually engage the crop, KUHN leaves nothing to chance: top-quality raw material has been wound into four coils with long tine fingers, giving you exceptional reliability. A defined attachment system to the arms results in an unmatched design life of at least 180,000 cycles. This provides several hundred hours of work before tine replacement is necessary. Asymmetrical tine finger length means both fingers engage the crop equally and sooner for a more consistent pickup. The tine guards prevent accumulation of debris around the coils and help retain broke tines from entering the tedded crop to minimized possible damaging harvesting equipment.

Asymmetrical Tine Length

The asymmetrical tine length with longer outer fingers has several advantage to bring the machine’s tedding quality to perfection. This allows the outer finger to touch the crop earlier compared to symmetrical tines. It also ensures more complete tedding, along borders and between the rotors, where the tines overlap more in this sensitive area. Contacting the crop sooner means that the actual working width of each rotor is expanded and as a result, the entire machine working width is expanded.

OptiTedd Rotors

OptiTedd rotors offer a steep angle of attack for complete crop inversion and fast, uniform drying. The improved rotor design increases robustness and ensures effective tedding in all conditions. Small-diameter rotors, available on GF 8703/7903/10803 models, feature a minimum distance to the center of gravity to reduce lift and horsepower requirements. Large-diameter rotors, featured on the GF 7803, excel at spreading long, dense crops.

Proven & Reliable Components

DigiDrive® Coupling System

When a KUHN engineer came up with this drive coupling design, we knew that it would revolutionize the rotary tedder. This patented design made it possible to reliably drive a large number of rotors, yet fold them for unmatched transport ease, all with virtually no maintenance or repairs. Since the DigiDrive coupling’s inception, nearly 20 years have passed and more than 150,000 KUHN tedders are now being used across the world to ted hay with the ultimate reliability.

The DigiDrive contains case-hardened forged steel fingers for improved wear resistance. Synchronization of rotational movement is outstanding both in work and in transport where the components are folded nearly 180° to reduce the machine’s space requirement. The DigiDrive is a highly reliable system requiring very little maintenance – no daily greasing necessary!

Rotor Housings – Made to Last

With rotors driven by DigiDrive couplings and lubed-for-life rotor housings, the greasing points are limited to a relatively few pivot points allowing you to spend more time in the field and less time greasing.
  • They are supported by large diameter, double-row angular ball bearings.
  • The thoroughly sealed rotor housing prevents lubricant leaks or introduction contaminants.
The robust mounting of housings to the edge of the rectangular frame maximizes strength and durability.

Headstock

The headstock has been tried and tested through years of experience. It is particularly suitable for this size of machine and features sturdy construction, effective recentering on slopes and reduced overhang.

Exclusive Suspension System

With the GF 1003 Series tedders, you will benefit from an exclusive and patented suspension system, which combines the advantages of powerful springs with those of hydraulic suspension.
    • The hydraulic suspension stabilizes the machine when maneuvering on headlands, no matter the field conditions. The tedder automatically and smoothly returns to the center, when it is lifted, due to the two large shock absorbers.
    • Integrated springs enhance the machine’s flexibility at the same time, always keeping it in the best working position.
    • The integrated rubber mounts absorb shocks on rough roads, while the absorbers control the machine movements.

    The whole system provides exceptional suspension and driving comfort. Even when braking suddenly in turns, the rotors remain stable and carefully aligned behind the tractor. You will appreciate this with ever increasing tractor speeds.

Headland Lift Control

Headland Lift Control makes tedders easy to lift and maneuver on headlands while limiting the introduction of foreign materials like dust into the forage. This is beneficial because the headlands do not need to be tedded twice. One hydraulic valve in the cab lifts all the rotors from the ground providing high ground clearance to pass over windrows and allows operators to easily turn on headlands or narrow areas. Available on GF 8703/10803 models.

Match Your Crop Conditions

Offset Border Tedding Along Field Edges

For clean, careful tedding next to fences or neighboring fields, GF 1003 tedders are equipped with a border control system. On slopes, the border setting is particularly beneficial for controlling the direction of crop spread and obtaining an optimal spread pattern.

Quick Adjustment of Tine Angle

Whether in long or short, wet or dry crop, or different cutting heights, the pitch angle is adjusted without tools near the wheel supports. Always remember a steep pitch angle will decrease drying time and increase the nutritional value of the forage.

Crop Deflectors

Operating in short, sticky crops or long, late season crops can be a challenge when the crop wraps in the wheel column, resulting in frustrating downtime spent clearing the mess. These tedders are fitted with crop deflectors as standard.

Ground Following

The ground following on these tedders matches that of smaller sized models in the GF Series. These machines have excellent ground following with their small rotors that are each less than 5’ in diameter, which allows for uniform tedding across the whole field. There is individual articulation between each rotor and equal spacing between the rotors and tires for better ground following.

Folding System for Narrow Transport

The folding system allows the transport wheels to lower and combine with the rotors tilting forward. While in transport position, height is reduced, load distribution on the tractors is optimal and road transport at higher speeds is ideal. The incredibly narrow transport width of 9’10”, results in easy maneuverability and stable road transport.
