Limiting the weight and loads on the tractor components were key criteria when designing the machine. These goals were reached thanks to the new design of the frame and mowing-grouping unit holding arms which allowed reducing the weight, increasing the compactness with a centre of gravity set 15 cm forward with regards to conventional machines. A notable weight reduction also comes from the belt conveyor frames made of aluminium. The reasonable weight is also an advantage at work: lower power requirement and limited soil compaction. Furthermore, the action of the hydro-pneumatic suspension facilitates ground following.
Remarkable stability, particularly for transport. The machine’s design limits load transfer on the rear axle, owing to its conveyor structures in aluminium and mowing units located closest to the tractor. The reasonable weight and optimized centre of gravity improve the tractor’s balance and stability for safe transport.
The front guards automatically retract in transport position for easier and secure access to the rear of the tractor! It is possible also to retract them when the machine is unfolded for easy access in order to replace knives or for machine cleaning. The mower can be stored in the vertical position to reduce the space requirement for winter storage.
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.
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.
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:
Maintenance is essentially limited to the drive components and a few pivot points, and at large intervals.
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.
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.
All machine controls are grouped on the tractor ISOBUS terminal or on the CCI 800 or 1200 options available. All machine functions, as well as the front mower, are easily controllable. At a glance, it is possible to view all settings and indicators. Functions such as the integrated headland turn sequence make it easier to operate the mower combination.

Adding an ISOBUS joystick such as the CCI A3 (optional) further improves comfort of use.
