GF 1012 range include 8 and 10 rotor tedders with working widths of 8.70 m and 10.80 m. Narrow fields will no longer be an issue for users of these mounted tedders thanks to the HLC (Headland Lift Control) rotor lift system . Simply activate the valve to lift the rotors a minimum of 50 cm off the ground, in less than 5 seconds.
They are also equipped with all the components that have made KUHN tedders such a great success over the years, both in terms of capacity and forage quality.

Quick and easy manoeuvres

The GF 10812 in HLC (Headland Lift Control) position

50 cm in less than 50 seconds with the HLC system

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:

Reverse into pickets and corners.
Headland turns made easy.
Acess multiple fields without folding the machine. Ditches are no longer a problem!

The high ground clearance of the rotors prevents any forage build-up when passing over larger swaths.

Ultra-compact for extra road safety

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:

Ideal road suspension.
Perfect stability during turns and in work mode.
Just the right weight balance between the machine and the tractor.

The GF 10812 is the most compact tedder on the market with work output reaching 10 ha/h.

Reduced maintenance

DIGIDRIVE: revolutionise tedding

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.

Rotor housings made to last

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!

Crop deflectors for clean wheels

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.

Top quality forage

High quality forage, even in corners

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:

Easily pass over large amounts of forage without any of it building up around the wheels. The forage is turned once only, including the headland areas.
Reverse on uneven ground without picking up impurities (soil, stones) due to the rotors touching the ground.

Top quality tedding

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:

Working with a wide angle of attack while turning the crop
Fast and uniform drying.
Fully effective crop inversion.
Uniform distribution.
Exceptional ground adaption.
Mounted tedders with less overhang to reduce lift requirements.
Reduced power requirement.

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.

Integral pick-up with asymmetrical tines

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.

User Stories:GF 1012

David Wilkes Farmer
“We looked at all the options and then decided to replace our existing Kuhn tedder with the newer model,” says David. “We need a strong and reliable machine as it’ll be expected to do a lot of work, and last us at least five years. We are tedding each crop as many as four times and possibly twice in a day, and timeliness can be critical, so being able to do a quality job whilst covering 15 – 16 acres an hour is important.
“The key difference with this newer model is the Headland Lift Control feature, which ensures all the rotors are lifted fully out of the crop at the headlands, thereby ensuring these areas remain evenly spread and are not over tedded. It is easy to pre-set the rotor height and speed, so operating at the headlands is effectively automated and the whole operation is a lot easier. The tedder is also very quick to fold into its transport position and is very compact when folded, and that’s important as we do need to move between fields quite a lot.”
