Kuhn updates its king-sized tedders

Kuhn has upgraded its range of large trailed tedders, with its 13 and 17.2 metre machines both benefitting from a new chassis design and rotor lifting mechanism.

Retractable straps also ensure the machine remains stable across its full width when working.

The GF 13012 features 12 rotors to give a working width of 13m while the 16 rotor GF 17012 has a working width of 17.2m. Minimum power requirement is about 80 and 100hp respectively.

 

For improved headland clearance, the two outer sections on both machines are supported and held in place by self-reeling tension straps which enable all 12 or 16 rotors to be lifted in one motion. As well as reducing stress on the main chassis and individual rotor sections, the straps also ensure the entire machine remains stable across its full width, says the manufacturer, even when moving over rough or rutted terrain.

 

When folding the tedder into its road transport position, an auto-reel device – similar to those used to tension car seat belts – automatically winds the straps away.

A new chassis design for Kuhn’s large tedders affords better field and road travel.

The whole tedder is hydraulically raised via a pair of transport wheels, with generous ground clearance as not to interfere with cut grass, says the manufacturer.

 

To follow contours, the rotor train moves independently of the carrying frame. When in use, the weight of the chassis is supported by the transport wheels, while the small diameter rotors are suspended separately. As a result, soil contamination and tine wear is reduced, says Kuhn.

 

Rotor height is adjusted via a single, hand-operated lever, while individual rotor pitch angle can also be adjusted without the need for tools.

 

A hydraulically controlled curtain deflector to prevent losses at field edges and borders is available as an option.

 

Retail prices for the GF 13012 start at £34,950 while the GF 17012 starts at £42,600.
