2026 Kuhn GF 1003 T Series 7803 THA

Optimize your field efficiency with the GF 1003 T Series trailed rotary tedders, ranging in size from 17’1” to 56’5”. Both versatile and adaptable, these tedders are designed for producers and custom operators to harvest more crop in less time by easily transitioning from work to transport.

KUHN GF 1003 T Series trailed rotary tedders are ideal for both custom operators and hay producers. 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 new OptiTedd rotors are the secret to rapid drying, excellent ground following and low incorporation of impurities in the crop, helping maintain maximum forage quality. 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. Each of the rotor gearboxes are sealed, lubed-for-life and driven by KUHN’s patented DigiDrive® system, reducing maintenance. Despite the wide dimensions at work, these machines are incredibly compact in transport.

Features may include:

• 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 7903 T/8703 T/10803 T/13003 T/17003 T models, feature a minimum distance to the center of gravity to reduce lift and horsepower requirements. Large-diameter rotors, featured on the GF 5203 THA/7803 T/7803 THA, excel at spreading long, dense crops.

• 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 for a more consistent pickup. The tine guards prevent accumulation of debris around the coils.

• 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.

• 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.

• Standard Headland Lift Control, available on select GF 1003 T Series tedders, makes the machine 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.
