Quad-rotor rake GA 14231

• KUHN introduces the GA 14231 quad-rotor rake with an extended working width of 13.70 meters to meet high-output demands.

• The machine features a 100% hydraulic drive system reducing daily servicing time by about an hour compared to mechanical systems.

• It includes the maintenance-free, robust MASTERDRIVE GIII gearbox capable of handling heavy forage.

• The BOOST function accelerates drying by increasing front rotor speed to create uniform windrows.

• Hydraulic suspension on front rotors adjusts ground pressure automatically and allows individual rotor lifting to protect terrain and adapt to field conditions.

• ISOBUS certification enables automated rotor control and simplifies operation through an intuitive terminal interface.

The GA 14231 rake with four rotors completes the range, with a new maximum working width of 13.70, to meet very-high-output requirements.

The new GA 14231 joins the existing 10231 series of quad-rotor rakes renowned for high output, flexibility, and impressive working quality. As the newest member, this model boasts an array of upgrades along with all the features that make these rakes so well appreciated.

Among the technical features, KUHN has developed a 100% hydraulic drive system. The daily servicing requirements of this system take around an hour less than a mechanical system, so precious time is saved, especially in unpredictable weather conditions.

Another time saving feature integrated into the GA 14231 rake is the MASTERDRIVE GIII gearbox. This gearbox is well-known for being robust and reliable with no maintenance requirements. In addition, due to its high operating capacity, it can work in heavy forage.

The rake comes with a BOOST function to speed up the drying process and facilitate harvesting. This function increases the speed of the front rotors by 20% in relation to the rear ones. The rotational difference sends the fodder towards the centre of the machine to form uniform, fluffy windrows.

To protect the sward and the cut fodder, as well as to adapt to working conditions, the machine’s front rotors integrate a hydraulic suspension system. This feature adjusts ground pressure automatically to working width. The rotors can also be raised individually to avoid obstacles and adapt to the shape of the plot.

Lastly, these quad-rotor rakes are ISOBUS-certified by the AEF. The different indicators, functions, and automatic features on the terminal interface make the machine easier and more practical for the user to operate. The Section Control function automates individual rotor lifting and lowering at headlands and in field points according to the areas worked, so the driver can concentrate on driving.
