FC 1025 F disc mower conditioners

Front mowing units must be flexible in order to adapt smoothly to all terrain variations. At the same time, they are often exposed to extreme loads. KUHN's FC front mowing units are designed to cope with this. The kinematics of the front-mounted mower-conditioners incorporate two robust lower links mounted on large ball joints. The pivoting points of the rods on the tractor side are closer to the ground than those at the front. This dynamic load on the mower unit provides the mowing unit with a high degree of ground contour following, especially in hilly terrain. The mower unit is also equipped with a pendulum joint and can be moved in all directions. It can be swivelled from left to right at an angle of up to 30° and can be moved vertically by up to 70 cm!

The new OPTIDISC ELITE cutterbar has been developed in cooperation with farmer users. The variable disc spacing, large cutting overlap and low mowing angle provide the desired mowing quality. Equipped with this cutterbar with the lastest updates, the FC 3125 F and 3525 F ensure clean and even mowing in all situations. The OPTIDISC ELITE cutterbar is equipped with several exclusive features:

• Where the discs diverge, the distance between them is reduced to encourage the knives to overlap. The mowing pattern is clean and neat, even in short or light forage. (A)
• At the point where the discs converge, the spacing is increased to provide more space for the crop flow. It is quickly discharged to the rear, so that the mower's work is not disrupted. (B)
• An area of overcutting that almost doubles its surface area for better quality cutting in wet and sticky soils (or presence of molehills) or in heavy and poured forages, plant cover harvested in late fall.
• A lower angle of cut: in close mowing, this prevents a mowing profile with typical undulations. This also promotes faster, uniform regrowth and easier adjustment of subsequent machines.
• New disc bearings with a unique shape and mounting always ensure that the knives are securely held in place during and impact and can be rotated through 360°.

In hilly terrain, wet conditions or sticky grass, soil can accumulate at front of the cutterbar, but not with OPTIDISC ELITE! Its specific skids improve the ground contor following and preserve the grass stubble. This can alos protect the quality of the forage, especially in difficult conditions.

The steel tine conditioner is very efficient in heavy, long or mature forage but also in short forage as it has a good throughput capacity. Can I have the french please - this does not make sense The power absorbed by this type of conditioner is limited thanks to the reduced time spent in the machine components and the absence of recycling. Well formed and aerated swaths are clearly the result of this steel finger conditioner. The position of the fingers causes the crop to swell and send it upwards before it falls back into the swath. The crop is optimally ventilated and is therefore richer in energy and nutrients thanks to the accelerated drying process.
The steel tines can also work in lucerne with the right conditioner setting.
You can adjust the conditioning intensity:

• By adjusting the deflector plate.
• The conditioner rotation frequency can be selected.

Tests carried out by Arvalis (French agronomic institute), the Chamber of Agriculture and the FD machinery cooperative highlighted the drying curves of different mower-conditioners (finger or roller, in plastic or steel). The mower-conditioner with the SQUAREFLEX polyurethane roller came out top with over 80% of DM by the second evening compared to the third evening with other methods.
Specific SQUAREFLEX roller treads in the polyurethane, grip the crop with a regular movement, no matter which direction the crop is leaning. Pressure is adjusted between the rollers with an easily accessible adjustment screw. In addition, the gap between the rollers can be widened to let foreign bodies pass through.
Both rollers are driven by a gearbox (no chains or belts!) They are synchronised for life: longer service life and no maintenance, Both rollers rotate at 780 min-1 to ensure optimum functioning in all conditions, with delicate forage as well as in ryegrass, sorghum and immature crops...
