Tedders GF 1003 T

Profile of the GF 1003 T tedder

Less drying time and higher yields

Maximize the potential of your fields with the GF 8703 T and GF 10803 T trailed tedders, available in two working widths (8.70 m and 10.80 m). These tedders are designed for large farms and contractors to harvest more forage in less time.

The GF 8703 T and GF 10803 T are tedders with 8 and 10 rotors, with a working width of 8.70 m and 10.80 m. Tight plots and headlands are no longer a problem for users of these trailed tedders thanks to the HLC (Headland Lift Control) rotor lift system. By simply operating a valve, all rotors are lifted at least 50 cm from the ground, in less than 5 seconds.
They are also equipped with all the features that have made KUHN tedders successful for many years, whether in terms of forage compactness or quality.

Your benefits

Fast and even drying of the forage

The new OPTITEDD rotor allows you to double the surface area you can ted

The new OPTITEDD rotor for a perfect forage!

The new OPTITEDD rotor pushes the limits in terms of resistance and lifetime of the working parts. It allows you to double the surface area you can ted. The design of the rotor, the arms and the tines means increased robustness so that the machine can work even in the most extreme conditions (heavy forage, stony ground, etc.).

The design of the rotor and the increase in the rigidity of the base plate greatly reduce vibrations. The stamping of the plate and the arm has also been reinforced.

Tine deflectors eliminate buildup on the tine arms, and prevent the forage from rising and wrapping around the tine and rotor. The "anti-loss" function prevents a tine being lost in the forage and damaging the following machines or polluting the ration.

Full pickup with robust and asymmetrical tines

The Heavy Duty tines fitted on this new rotor have a service life that is double that of standard models. The 10 mm diameter of the strand and 4 large diameter coils (80 mm) contribute to a strong reduction in tine fatigue without altering the flexibility necessary for work. The tedding quality is preserved while stresses and strains on the tines produced by heavy forages are reduced.
The asymmetrical length of the tines, with a longer outer tine, offers certain benefits for quality tedding. Compared to a symmetrical design, the outer tine engages the forage earlier. This ensures that the forage is picked up completely, even at the edges of the field, but also between the rotors, with better tine coverage in this sensitive area. An earlier pickup of the forage means that the actual working width of each rotor, and thus of the machine, is greater.

The advantages of small diameter rotors

The experts are convinced. Thanks to the small diameter rotors, you will gain in forage quality.
According to the Chamber of Agriculture Weser Ems in Germany, you will gain 33% more drying time. The experts at DLG (agricultural technical organization) consider the forage is completely turned over and the distribution quality of the grass is even. View the test results!
Farmers who have used them can no longer go without them. Their many benefits are essential for the production of top quality forage.
When working with a large pitch angle, pick up the entire forage and benefit from:
  • A quick and even drying.
  • A complete turning over of the forage.
  • Unparalleled cross-sectional distribution.
  • Exceptional ground adaptation.
The individual joints of the rotors and the identical spacing of each of them, combined with asymmetrical tines, ensure that the entire forage is picked up. This also applies to long or dense forage, including on uneven ground. Adjust the pitch angle in 2 minutes without tools to adapt to the volume of the forage.
The small diameter OPTITEDD rotor ensures that the whole forage is turned over

Quick adjustment of the tine angle

Whether you have long or short, wet or dry forages, or different cutting heights, the tine angle can be adjusted without tools near the wheel supports. Always remember that a high angle of inclination reduces the forage drying time and increases its nutritional value.
The tine angle is easily adjustable on the GF 8703 T and GF 10803 T tedders.

Reduced maintenance

DIGIDRIVE training: the revolution

When KUHN invented this drive design, tedding entered a new era.
From that moment on, it became possible to drive a very large number of rotors, fold them with an unequaled compactness and without any maintenance. A veritable revolution!
Since the introduction of the DIGIDRIVE finger coupling, more than one million rotors have been used around the world for tedding forage with outstanding reliability. The DIGIDRIVE coupling is made of case-hardened steel and requires no maintenance.

Rotor housings designed to last

The guide is made by large double-row angular contact ball bearings. The sealing is reinforced to prevent lubricant leakage and the introduction of impurities. It is firmly attached to the rectangular structure by means of spacers with long through screws. Thanks to these housings, lubrication on the machine is limited to a few pivot points.
Maximize time spent in the field and minimize maintenance time!
The rotor housings of the Tedders GF 1003 T Series are built to last.

Deflector plates for clean wheels

Tedding young, sugar-rich or long, late forages can be tricky if the strands wrap around the wheel columns. This inevitably leads to downtime while the problem is being resolved. Take advantage of the deflector plate equipment to prevent the forage from wrapping around the wheel columns.
The deflector plates on the Tedder GF 8703 T prevent forage from wrapping around the wheel columns.

Quick and easy maneuvers

50 cm in less than 5 s with the HLC (Headland Lift Control) system.

Take advantage of the quick response of the HLC rotor lift system at headlands. You will reach 50 cm of height under the central rotors and even more on the ends.

Gain in reliability and work output by maneuvering easily:
  • Reverse at the headlands.
  • Easily turn at the headlands.
  • Cross your fragmented plot of land without folding your machine. Ditches are no longer a problem!
The large rotor clearance prevents forage build-up when maneuvering over bulky swaths.

Quality forage, even at the headlands

The HLC system greatly improves the tedder's response when moving backwards and maneuvering in order to ensure the quality of your forage, over the entire plot, even in the narrowest plots. The height of the HLC rotor lift system is impressive and allows:
bulky forage to be easily crossed over without the risk of it building up around the wheels. The forage is only turned once, thus avoiding multiple turnovers in the headland areas.
To reverse on uneven ground without introducing impurities (earth, stones) into the forage.
The HLC system on the Tedder GF 8703 T improves the tedder's response and ensures quality forage.

Ultra-compact for more safety on the road

Absolute comfort on the road.
In terms of transport compactness it is one of the best on the market (3 meters wide and respectively 3.15 and 3.30 meters high for the GF 8703 T and GF 10803 T). This provides great maneuverability and facilitates travel.
The 3-point linkage and the cleverly placed transport wheels allow the necessary weight transfer between the machine and the tractor when lifting the rotors for headland turns or for folding/unfolding.
Maneuvering is made easier thanks to the large transport wheels (300 mm), placed close to the machine's pivot axis.
This ensures that the machine is responsive when working in curves, making it easier to drive.
