2025 Kuhn GF 1003 Series 10803

2025 Kuhn GF 1003 Series 10803

With 6 to 10 rotors and working widths of 21’4” or 35’5”, KUHN GF 1003 Series mounted rotary tedders combine ideal characteristics for high-quality work, overall efficiency, time savings, and great forage quality.

KUHN GF 1003 Series mounted rotary tedders, with working widths of 21’4” 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.

Features may include:

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.

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 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 6503 and GF 7803, excel at spreading long, dense crops.

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.
