Areas to mow are continuously increasing in size, while optimal mowing periods are limited. Reducing the rate of impurities from 4 to 2 % allows savings of up to 89€/ha/year*. That is why it is so important for farming operations to harvest dirt-free forage. You can count on KUHN solutions for efficiency, work quality and reliability.
With the FC 9330 RA and FC 9830 RA mower conditioners with swath grouper, it is now possible to group some forage-types as soon as they are cut.
Couple an FC 3125 F or FC 3525 F (only FC 3525 F for the FC 9830 RA model) at the front to benefit from KUHN's know-how.

A new mower design

Reduced weight combined with compactness on a large model

Limiting weight and stress on tractor components are key criteria in machine design. As such, a brand-new frame concept and support arms for the mower-grouper units make the machines lighter and more compact, and the centre of gravity is 15 cm further forward compared to conventional machines. The conveyor belt frames are made of aluminium, further reducing machine weight. A lighter weight is also an advantage at work: lower power requirement and less soil compaction. In addition, the hydro-pneumatic suspension system improves ground following.

A large width machine easy to manoeuvre

These machines are remarkably stable, particularly for transport. The aluminium conveyor-structure concept and mowing units positioned very close to the tractor mean less weight is transferred to the rear axle. The lighter weight and optimized centre of gravity improve tractor stability for safe transport.

A compact machine with easier access

The front guards automatically retract in transport position for easier and secure access to the rear of the tractor! It is also possible to retract them when the machine is unfolded for easy access when replacing knives or cleaning the machine, for example. All models can be stored vertically to reduce the space required for winter storage.

You can easily access the rear of the tractor: the mower's front guards retract in the folded position

Quality work with ground following

The OPTIDISC ELITE cutter bar offers excellent quality of cut

Benefit from the OPTIDISC ELITE cutter bar

The 2 mowing units are fitted the OPTIDISC ELITE cutter bars with 8 discs and 3.50 m working width. For optimum work on bends or slopes, the cutting overlap with a front mower conditioner FC 3125F is 42 cm per side! Clean forage is the key to success for savings in concentrates to be added into the herd's feed. The varying spacing between discs, the large overlap areas and small mowing angle of the OPTIDISC ELITE cutter bar provide the much sought-after quality.
Where discs diverge, spacing is reduced for increased knife overlap. Clean mowing even in short or light forage.
Where discs converge, spacing is larger, offering more space for forage to flow. It is quickly expelled rearwards, the mower work is not disturbed.
On hilly grounds, in wet or sticky grass conditions, soil can build up in front of the cutter bar, except with the OPTIDISC ELITE! Its specific skids improve gliding and preserve the sward. Another benefit for forage quality especially in difficult conditions.

Maximum reliability and hold

The cutter bar has been designed to cope with obstacles. With the PROTECTADRIVE safety system, in case a disc hits an obstacle very violently, the shaft holding the disc shears above a cleverly dimensioned shearing groove above the bearing. Gearwheels are protected. In less than 15 minutes, the machine is operational again at a very low repair cost.
The bearing is fastened by long screws, going through the cutter bar. Risk of bearings being torn out in case of a shock is prevented.
High-end components reinforce the core of the cutter bar:
- cutter bar with special double row angular contact ball bearings.
- Large diameter gearwheels in high precision forged steel with 3 teeth intermeshing.
- Discs with forged and fully heat treated cups.
- Heat treated steel disc skids with possibility of adding protective lining (fastening per screw).
To increase the machine's service life, dampers are fitted between the cutter bar and the frame. When mowing at high ground speed, the machine structure is less affected by shocks.

The PROTECTADRIVE safety protects the cutter bar in case of a very violent shock

Maintenance reduced to the minimum

Maintenance will not take all your time.
The OPTIDISC ELITE cutter bar is an excellent example of added value created thanks to the close cooperation between manufacturer and farmers. This solution is fully adapted to the practice and helps you save time owing to:

Life-lubrication. Maintenance-free cutter bar.

The fully safe FAST-FIT knife attachment system comprises a leaf spring ensuring constant pressure on the fastening screw for further safety. Knife replacement requires little time.

Maintenance is essentially limited to the drive components and a few pivot points, and at large intervals.

Save time with the FAST-FIT quick knife release system

NON-STOP safety system combined with the LIFT-CONTROL suspension

During the high season, nobody can afford to damage the mower because of a forgotten obstacle, or even a wrong manoeuvre.
When encountering an obstacle, the concerned mower unit shifts rearwards around a pivot point. The mower unit automatically returns to the initial position without stopping

The safety remains effective even if the obstacle is struck by the inner discs of the mower unit, since the pivot point of the arm is sufficiently far from the first discs.

The front edge of the mower unit rises slightly, providing additional clearance.

With the LIFT-CONTROL suspension and the NON-STOP safety system, the mowing unit is protected from obstacles

High-performance and easy-to-adjust conditioning

The new conditioner with metal fingers contributes to the weight reduction of the machine. The lever-controlled two-speed gearbox offers the possibility of operating the conditioner at a slower speed to preserve the most delicate forages. Conditioning is easily adjusted to suit forages and weather conditions. The standard recycling plate (placed between mowing unit and belts), prevents forage loss.
The conveyor belts are driven by 2 pumps supplied by a tank integrated into the central frame. The other hydraulic functions use a hydraulic unit connected in load sensing to the tractor (folding, lifting-lowering on headland, conveyor positioning, suspension). This design avoids significant hydraulic requirements during work, eliminates overheating and increases the responsiveness of machine functions. The tension of the belts is set centrally, quickly and with ease.

ISOBUS technology available on a mower

Find all controls of your FC 9330 RA mower conditioner on your ISOBUS CCI terminal

Control all functions with ISOBUS

The electronics are key in making the FC 9830 RA mower conditioner efficient and easy to use.User-friendly interface: The work screen is intuitive and easy to use allowing operators to adjust settings quickly and monitor machine performance.Controlling the mowing units: The mowing units can be controlled from the terminal: simultaneous or individual raising and lowering. By simply pressing the GO-END button, the operator can perform headland sequences where front and rear units are raised and lowered in a preset sequence easily adjustable by the user. Controlling the conveyors: Conveyor speed, offset, as well as raising and lowering are controlled with the terminal or an AUX-N joystick. It's also possible to perform left/right mowing with one belt in grouping position and the other in wide-delivery position to group 18 m of forage. This makes the swath easy to pick up with a 4-rotor rake.Mower-unit lift-control: lift-control can be adjusted from the cab directly to suit operating conditions and working speed. This reduces energy consumption and wear.AUX-N function: Thanks to the AEF AUX-N certification, it is possible to use auxiliary controls, such as the CCI A3 joystick. This enables the operator to view all the machine's control functions directly on the touch screen, and to select the right function at the right time. Folding/unfolding: A single operation on the ISOBUS terminal or joystick activates the mower conditioner's automatic folding or unfolding sequence. The driver can work in total safety and save time when setting the machine to transport position.Area counters: The driver can monitor the area covered, precisely, making the job easier to manage.

Even more practical with Section Control

As well as displaying the areas already mowed, the integrated TC-SC function automatically controls each rear mowing-unit and the front-mower raising and lowering, via GPS. This eliminates overlapping and increases operating comfort.

The TC-SC function is integrated into FC 9330 RA and FC 9830 RA mowers.
