Equipped with 6 large rotors with 7 tine arms, the GF 7802 TGII is the ideal machine for spreading voluminous swaths.
Large diameter rotors have been specially designed to handle long, dense forages.
Experts are convinced and those who have used them can no longer do without them. The many benefits of small rotors are essential for those who want to produce top quality forage:
The semi-mounted GF 7802 T G II and GF 7902 T G II are among the most compact tedders on the market. This provides great manoeuvrability and makes travel easier. They are easily coupled to all tractors with a Category 2 3-point hitch.
Practical: In hilly areas, it is possible to lift the front of the rotors slightly to facilitate crop flow.
The lowering motion of the transport wheels is combined with the forward tilt of the rotors. Thus in the transport position, the height is reduced, the load transfer on the tractor is optimal and the road behavior at high speeds is perfect.
To reduce the weight on the wheels of the central rotors, a transport undercarriage is placed at the front of the rotors.
Only part of the weight rests on these central wheels. The rest is taken over by the drawbar and tractor.
The benefits are obvious:
In bumpy terrain, for an adapted ground following, a set of two complementary wheels mounted on a swinging beam can be mounted in front of the rotors.
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, to fold them with unmatched compactness and this without any maintenance. A real revolution!
Since the launch of the DIGIDRIVE finger drive some 20 years ago, more than a million rotors have been working the world’s terrain to ted forage with exceptional reliability. The DIGIDRIVE is made of case-hardened steel and requires no maintenance.
Guidance is carried out by large double-row angled ball-bearings (1). Their sealing is reinforced to prevent leakage of lubricants and any introduction of impurities (2). Robust fastening on the rectangular structure thanks to the spacers long screws (3). Thanks to these gearboxes, lubrication on the machine is limited to a few pivot points. Maximise field time and minimise maintenance time!
The tedding of young, high-sugar or long and late forages can be tricky if the strands wrap around the wheel columns. This inevitably leads to downtime to address the problem. Take advantage of the deflector equipment to avoid forage wrapping around the wheel columns.
The asymmetrical length of the tines, with a longer outer tine, offers some advantages for quality tedding. Compared to a symmetrical design, the outer tine engages earlier in the forage. This ensures full forage collection, even around the edges of the fields, but also between the rotors (C) (E), with better tine overlap in this sensitive area. Working the forage earlier means that the actual working width of each rotor, and therefore of the machine, is larger.
Experts are convinced of this; thanks to the small diameter rotors, there is an improvement in the forage quality. According to the Weser Ems Chamber of Agriculture in Germany, save 33% more drying time. As for the experts of the DLG (agricultural technical organisation), they believe that the forage is fully turned over and that the quality of grass distribution is even. See the test results!
The farmers who used them can no longer do without them. Their many advantages are essential for the production of top quality forage.
When working with a large pitch angle, the whole forage is picked up and you will enjoy:
The individual joints of the rotors and the identical spacings of each of them, combined with asymmetrical tines, ensure a full forage pick-up. This also applies to long or dense forage, including on uneven terrain. The pitch angle is set in 2 minutes without tools to adjust to the volume of forage.
