This tedder offers an exceptional quality of work. Its small rotors and asymmetrical tines ensure complete forage pick-up and even spreading. Ground following is optimized and responsive thanks to the chassis wheels placed as close as possible to the working part, which limits introducing impurities into the forage and preserves the plant cover. The GF 13003 T model is sized for intensive use. You can count on its robust and maintenance-free rotors. The risk of breakdown and downtime for daily maintenance are reduced. The ease of use of the machine was an objective of its development: it does not use a control box, no sensor, a single hydraulic valve is enough!
The GF 13003 T tedder is a perfect machine for tedding large areas, quickly and easily.

Your benefits

Forage quality

The rotors of the GF 13003 T tedder follow ground contours perfectly thanks to the GSC system

The soil is not scraped and the forage quality is preserved

The GF 13003 T tedder follows ground unevenness like its narrow-width counterparts.
This excellent ground following is made possible by the exclusive GSC (Ground Save Control) system. This system is characterized by a new concept allowing to have a very small distance between the wheels of the frame and the rotors. For the user, it is the assurance of having excellent ground following responsiveness, even on the most uneven terrain.
Some exceptional features:
  • When working, the weight of the frame rests on the wide transport wheels.
  • The small-diameter rotors ensure efficient turning and quick drying of the forage.
  • No need to invest in and adjust an additional guide wheel
Finally, a joint between each rotor combined with the highly reduced distance between the rotor wheel and the tines allows improved protection of the plant cover, limits introduction of impurities into the forage as well as tine fatigue.

An OPTITEDD rotor with a service life lasting twice as long

The new OPTITEDD rotor pushes the limits in terms of resistance and service life of working parts. The design of the rotor, arms and tines provides increased robustness allowing the machines to work in the most extreme conditions (heavy forage, stony ground, etc.).

The design of the rotor and the increased rigidity of the plate greatly reduces vibrations. Stamping of the plate and the arm has also been reinforced.

The Heavy Duty tines mounted on this new rotor have a service life that is doubled compared to previous models. A prong diameter of 10 mm and 4 large-diameter coils (80 mm) contribute to a strong reduction in tine fatigue without altering the flexibility they need for work. Tedding quality is preserved while internal stresses and constraints on the tines is reduced in the presence of heavy forage.

Tine deflectors make it possible to remove the load on the tine arms, and prevent forage from moving up and wrapping around the tine and rotor. The "anti-loss" function prevents tine loss in the forage and therefore damage to the following machines or ration pollution.

Small rotors, great results: 33% gain in drying time

Experts are convinced and those who have used them can no longer do without them. The many advantages of small rotors are essential for those who want to produce top quality forage
  • Working with a large pitch angle while picking up all of the forage.
  • Even and fast drying.
  • Complete turning over of the forage.
  • Unrivalled transverse distribution.
  • Exceptional ground adaptation.
The table below shows the impact of different pitch angles on tedding efficiency.
A large angle considerably reduces drying time.
Asymmetrical tines fitted on the OPTITEDD rotor allow full forage pick-up.

Forage fully picked up with asymmetrical tines

The asymmetrical tine length, with a longer outer tine, offers certain advantages for quality tedding. Compared to a symmetrical design, the outer tine engages the forage sooner. This ensures complete forage pick-up, even at field edges, but also between the rotors, with better tine coverage in this sensitive area. Working the forage earlier means that the effective working width of each rotor, and therefore of the machine, is larger.

An easy-to-use tedder

Owing to the HLC system, headland turn manoeuvres are easily made

Easy headland turn manoeuvres

The HLC (Headland Lift Control) system for lifting the rotors makes your life easier. Simply operate the hydraulic valve to simultaneously lift the rotors from the ground in less than 5 seconds when turning around at the end of the plot or in pointy part of the plot for example. The large clearance of the rotors prevents any forage buildup when manoeuvring over the mower swaths. The large clearance avoids turning the forage a second time and thus preserves the forage quality. Finally, thanks to the HLC system, pass over the most constraining obstacles without risk of damaging the working parts of the machine.

Very easy setting into working or transport position

Manoeuvres are carried out quickly to save time between plots
Reliability and simplicity are met: no sensors or control box. A single DA valve is enough and controls all phases and functions of the machine
Fast and simple setting into transport position with the GF 13003 T tedder

Simple maintenance and settings

Teh manual setting of the rotor working height is easy and fast.

Tool-free simple settings

Adjusting the pitch angle of the rotors is quick and easy. A few seconds are enough to adjust the pitch angle of a rotor without tools, nor risk of losing an pin or a lynch pin. You can therefore easily adapt your machine to your working conditions.
Similarly, adjustment of the tedding height is achieved by adding or removing shims. Simple and fast!

The DIGIDRIVE finger couplings and robust gearboxes: the revolution

When KUHN invented this drive design, tedding entered a new era.
From that moment it became possible to drive a very large number of rotors, to fold them up with unparalleled compactness and this without any maintenance. A real revolution!
Guidance is provided by imposing double-row angular contact ball bearings. Sealing is reinforced to prevent any leakage of lubricant and any introduction of impurities. The attachment is robust on the rectangular structure thanks to the spacers housing long through screws. Thanks to these housings, lubrication on the machine is limited to a few pivot points.
Maximize time spent in the field and minimize maintenance time!

Since the launch of the DIGIDRIVE finger coupling, more than a million rotors roam the reliefs of the world to ted the forage with exceptional reliability. The DIGIDRIVE finger coupling is made of case-hardened steel and requires no maintenance.

Deflector plates for clean wheels

Tedding young, sugar-rich or long, late forage can be tricky if the strands wrap around the wheel columns. This inevitably leads to downtime to remedy the problem.
Take advantage of the deflector plate equipment to prevent forage from wrapping around the wheel columns

Keep all your forage on your plot

Losses by forage spreading onto neighbouring plots are avoided thanks to a hydraulically controlled windrow curtain for borders. All the fodder is kept in the plot!
The curtain is very simply set up from the cab and does not require an additional hydraulic valve.
