The models with four rotors have a rotor diameter of 1,44 m. The ALPINHIT 6.6 has a rotor diameter of 1,30 m. Both of these rotor units are equipped with five tine arms and deliver unbeatable working results, because:
Small rotors adapt ideally to bumpy ground and reduce the amount of crude ash entering the forage.
They pick up smaller portions of crop, resulting in neater forage handling.
You do not have to spread the forage so widely, which results in an exact spread pattern with homogeneous lateral distribution.
They can be operated at lower speeds because they do not have to spread the forage as far. That is how disintegration losses can be avoided.
At PÖTTINGER, we insist on different length tines. That is because they have the decisive advantage that both legs are at the same distance from the ground.
As a result, the tine unit picks up the forage cleanly and evenly from the ground.
The inner tine leg does not scrape the ground and therefore does not contaminate the crop.
The outer tine leg picks up the forage earlier and stays at ground level longer, improving the overlap of two adjacent rotors.
The curved tine carriers ensure that the tines are firmly secured. They also give the tines extreme resistance and ensure that they do not spring back and let go of the forage too soon.
Sufficient space between the tine springs and the tine arms enables the best elasticity and movement.
To ensure contamination-free pick-up of the crop, the tines and rotor wheels on HIT tedders function as a perfectly coordinated system.
The rotor wheels are located very close to the arc of tine engagement. This ensures optimum ground tracking of the tines.
To minimise forage contamination, the tines should pass at least 3 cm above the ground.
The rotors can be moved into three positions. Using this system you can easily adapt the rotors to the forage conditions. A uniform and tidy spread pattern is ensured as a result.
Two tine angles can be set by turning the tine mounting through 180 °. Use this to set the tines in a dynamic or sweeping angle, depending on the forage.
For very dense, heavy forage, use the more dynamic angle to increase the spreading effect.
