OPTIMER L 9000 and 12000: KUHN disc stubble cultivators specially designed for large farms

KUHN launches the OPTIMER L 9000 and 12000, a new range of independent disc stubble cultivators with respective widths of 9 and 12 metres. These stubble cultivators meet the requirements of large farms looking for the best performance: high work output, optimal comfort level and uncompromising reliability without compromising work quality.


This wide width range was designed based on an in-depth study to meet all operating requirements of large farms. The high quality materials make the chassis of the OPTIMER L 9000 and 12000 amazingly robust.

No doubt that the KUHN OPTIMER L 9000 and 12000 independent disc stubble cultivators will appeal to professionals looking for the best financial and agronomic results for their farms.

The Steady Control ground tracking system on the OPTIMER L 9000 and 12000 is a real KUHN exclusive. Each chassis section is independent for perfect ground following. The pressure on the extension cylinders is hydraulically controlled to ensure that the discs penetrate in all conditions. The working depth is kept constant over the entire width of the tool, which reduces fuel consumption.

The OPTIMER L 9000 and 12000 offer a work output of up to 18 ha/h thanks to their width of 9 and 12 metres, at an average speed of 15 km/h. The range has the highest under-chassis clearance on the market to be able to work in all types of residues without unwanted stoppages. They are equipped with independent 510 mm discs with an elastomer safety system to ensure uniform work across the entire width of the machine. The double U roller offers uniform tamping due to the soil-to-soil contact without the risk of clogging.

Comfort of use is essential on wide machines, which is why the depth adjustment is hydraulically assisted. In addition, switching from working position to transport position is easily and safely made with just one command. During transport, the OPTIMER L 9000 and 12000 comply with EU regulations, with road dimensions of 3 metres wide by 4 metres high, and the stability is ensured thanks to the machine’s central axle.
