Take advantage of the quick response of the HLC rotor lift system at headlands. You will reach a 50 cm height under the central rotors and even more on the end rotors.
Gain in reliability and work output thanks to easy maneuvering:
The large rotor clearance prevents any forage buildup when maneuvering over bulky swaths.
Attach these tedders to tractors of 80 hp or more.
On the road as well as in a building, our tedders have been designed for you to gain in space and maneuverability
Width and height do not exceed the standard road gauges (3 meters wide and 3.25 and 3.65 meters high respectively for the GF 8703 and GF 10803).
It is easy to access plots thanks to the reduced length and large clearance under the rotors. The patented system of connection between the headstock and the beam of the machine simultaneously ensures:
The GF 10803 is the most compact tedder on the market. Its work output reaches up to 10 ha/h.
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 unequalled compactness and without any maintenance. A real revolution!
Since the introduction of the DIGIDRIVE finger coupling, more than one million rotors have been used around the world for tedding forage with an outstanding level of reliability. The DIGIDRIVE coupling is made of case-hardened steel and requires no maintenance.
Guidance is provided by large double-row angular contact ball bearings. Sealing is reinforced to prevent any leakage of lubricant and any 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!
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 HLC system greatly improves the tedder’s response when reversing and maneuvering in order to ensure the quality of your forage, over the whole plot, even in very narrow 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 wrapping around the wheels. The forage is only turned over once, thus avoiding multiple turnovers in the headland areas.
To reverse on uneven ground without introducing impurities (earth, stones) into the forage.
The new OPTITEDD rotor pushes the limits in terms of the resistance and service life of the working parts. The design of the rotor, arms and tines provides increased robustness allowing the machines to operate in the most extreme conditions (heavy forage, stony ground, etc.). with this new rotor, the area tedded will be twice as large.
The design of the rotor and the increase in the rigidity of the plate greatly reduce vibrations. The stamping of the plate and the arm has also been reinforced.
The Heavy Duty tines mounted on this new rotor have a service life that is doubled compared to previous 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. Tedding quality is preserved while the stresses and strains on the tines produced by heavy forages are reduced.
Tine deflectors eliminate loading on the tine arms, and prevent the forage from moving up 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.
The asymmetrical length of the tines, with a longer outer tine, offers certain advantages for quality tedding. Compared to a symmetrical design, the outer tine engages with 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 pick-up of the forage means that the actual working width of each rotor, and thus of the machine, is greater.
