Benefit from the HLC system that raises the rotors at headlands. Your central rotors will reach a height of 50 cm and the outer ones will rise even higher.
You’ll feel more confident and gain work output with these easy and manouverable teddersl:
The high ground clearance of the rotors prevents any forage build-up when passing over larger swaths.
Couple these tedders to tractors from 80 hp.
Whether on roads or in the shed, our new tedders have been designed to save space and to be easy to manoeuvre operator comfort is a must!.
Width and height do not exceed classic road dimensions (3 metres wide and 3.25 and 3.65 metres high respectively for the GF 8712 and GF 10812).
Field access is easy with the shorter transport length and considerable ground clearance. The patented linkage system between the headstock and the beam ensures:
The GF 10812 is the most compact tedder on the market with work output reaching 10 ha/h.
When a KUHN engineer invented this drive concept, tedding entered a new era.
From that moment on, it became possible to drive a very large number of rotors and fold them to an incredibly compact size, and all this without any maintenance. A real revolution!
Since the launch of the DIGIDRIVE finger drive system twenty years ago, more than a million rotors have been working all around the world, tedding forage with exceptional reliability. The DIGIDRIVE system is made of case-hardened steel and requires no maintenance.
The guidance is done large-diameter, double-row angular ball bearings (1). Thoroughly sealed to prevent lubricant leakage and impurities getting in (2). Robust mounting on the rectangular frame with spacers and long through-bolts (3). With these rotor housings, greasing points are limited to a few pivot points, allowing you to spend more time in the field and less doing maintenance!
Operating in young sugar-rich crops or long late-season crops can be a challenge. Forage can get wrapped around the wheel columns resulting in downtime spent cleaning it off. Benefit from crop deflectors, for models from GF 5902, that prevent forage getting wrapped around the wheel columns.
The HLC system improves tedder reactivity considerably when reversing and manoeuvring. This ensures the quality of your forage over the entire plot, even in the narrowest field. The impressive height of the HLC rotor lift system means you can:
Experts are convinced. Small rotors produce better quality forage. According to the Weser Ems Chamber of Agriculture in Germany, they provide 33% faster drying time. The experts from the DLG (Agricultural techniques organisation) say that small rotors provide complete crop inversion and produce uniform grass distribution. View the test results!
Experts are convinced and those who use them swear by them. For farmers whose goal is to harvest a first class crop there are so many advantages to having small rotors:
The individual rotor joints, identical spacing and asymmetrical tines ensure that all the forage is tedded, even when it is long or dense and on uneven ground. Adjust pitch angle in just 2 minutes (no tools required) to adapt to the quantity of forage.
Asymmetrical tine length with longer outer fingers produces high quality tedding. The outer finger moves into the forage earlier compared to a symmetrical design. This ensures a more complete tedding operation, even on field borders and between rotors (C) (E), due to better tine overlap in this tricky area. Moving into the forage earlier means that the actual working width of each rotor (therefore the machine) is larger.
