Ultima CS

Optimal plant distribution

The seed is placed in bands of 6 cm width each. The distance from band centre to band centre is approx. 18.5 cm. This improves the distribution of the plant stand and provides an optimum supply of nutrients and reduces disease infestation. The robust tines as the sowing unit, with a coulter load of more than 230 kg, optimally maintain the preset depth. This is important for shallow sowing such as rape or deep sowing such as field beans and peas.

Operation of the Ultima CS

The soil in front of the seed coulter is first packed, then the coulter opens the seed slot by clearing away straw and dropping the seed onto water-bearing soil. Subsequent leaf spring levellers level the soil again before the STS packer roller performs the final reconsolidation.

Adjusting the working depth

The single-acting hydraulic cylinders of the sowing units are used to adjust the working depth and at the same time act as shock absorbers in the event of stones and large irregularities in the field. They also prevent vibrations from being transmitted to the machine frame. This keeps the machine smooth, even at high working speeds of 15 - 20 km/h.

Seed placement with seed tines

A leading support roller scans the contour of the soil. The following seed tine follows the support roller and precisely maintains the set placement depth. Changes to the placement depth can be adjusted hydraulically from the tractor. All sowing elements are connected to each other via hydraulic lines. In the event of obstacles, such as large stones, the tines can swerve without being damaged.

Tines and coulters

The Ultima CS is equipped with the 60 mm coulter as standard. As an option, there is the TC coulter with the corresponding tine. The TC coulter is only 15 mm wide and reinforced with tungsten carbide at the tip. It is ideal for direct seeding, as little soil is moved during work. This leaves a protective layer of plant residues from the previous crop on the surface. Under these conditions, drying out of the soil is delayed and erosion by wind and water is reduced.

Seed tank

A large tank opening and the low design of the machine facilitate the filling process of the large tank. Depending on the model, the tank holds a volume of 2,700 litres to 3,300 litres.

Centrally located undercarriage

The undercarriage is located centrally in the machine, enabling a tight turning circle on the headland. This means that even small patches can be worked efficiently without creating damaged compaction on the headland. The undercarriage is completely lifted during work.

Tram line marker

With the massive tram line marker, markings can be optimally created for the connecting runs. The large, discs leave a clearly visible track and are individually adjustable.

Hydraulic Levelboard

The hydraulic level board is used for levelling and removing tracks on the plough furrow and during mulch sowing. At the same time, it supports the machine in the front area and ensures smooth running.

Seed flow control

For monitoring all seed hoses Köckerling offers an optional seed flow control. A signal is immediately triggered, if a fault actually occurs in the hose system.

Half-side shut-off

To prevent too much seed being sown twice in the event of overlaps, e.g. due to certain tramline rhythms or at the end of the field, the Ultima CS can be equipped with half-side shut-off. In this case, the outlets of the distributor head are fitted with adjusting flaps, which can then be closed at the push of a button, if required. The seed rate is adjusted accordingly.

Hillside disc

To ensure that the machine always works on track even on sloping terrain, the use of a hillside disc is recommended. The disc has a diameter of 700 mm and is mounted centrally next to the transport chassis. A spring-loaded suspension on the hillside disc ensures operational safety, even when you work with the machine on stony terrain.

Pre-emergence marker

Optionally, the Ultima CS can be equipped with a pre-emergence marker. The discs leave a very visible mark for the following operation.
