Tedders from Kuhn
In 2022 KUHN launched 13, 15 and 17 metre wide tedders which fold twice as fast as the outgoing models and are fitted with new rotors and tines that are expected to last twice as long. The GF series also features a new reversible draw bar that will enable the tedder to be hitched to a wider range of tractors.

The GF 13003 T is likely to be a popular model and replaces the outgoing GF 13012 to offer operators an improved tedder with new rotors and tines. KUHN has concentrated on saving time and extending the life of the machine. It still has 12 rotors, but these have been upgraded to reduce wear.
The new tines are expected to last twice as long as those on the outgoing model due to an increase in the tine diameter and stronger springs. The new tines are 10mm wide and have upgraded springs that have increased from 70 millimetres to 80 millimetres. The wider tine, with a larger and stronger spring, makes the GF tedders more resilient than the previous models which is expected to double the life of the tines.
The folding mechanism on the new machines is twice as fast as the outgoing model. A new single movement, folding mechanism works directly off a tractor spool with no control box or electric sensors needed. By creating a single movement, KUHN has reduced the folding and unfolding time to just 2025 seconds.
Anti-loss function on the tine is now a standard feature and offers the ability to set the tine height hydraulically. The new models also have improved ground adaption thanks to the choice of new wheels which will help operators calibrate the tedder to the ground conditions.
KUHN’s Ground Save Control (GSC) system allows the rotor train to move independently of the carrying frame.
When in use, the weight of the chassis is supported by the large transport wheels, while the small diameter rotors are suspended separately, enabling each rotor to follow the contours of the ground without scraping the soil. This not only prevents the crop from being contaminated by dirt, but also reduces tine tip wear.
