The Kuhn Optimer L 9000 is a trailed disc harrow designed for soil preparation and seedbed cultivation. Kuhn is a recognised European manufacturer of agricultural machinery serving arable farming and soil management across multiple continents. Disc harrows are essential implements for breaking up and levelling soil after ploughing, incorporating crop residues, and creating fine tilth ahead of sowing.
This machine features a working width of 9 metres and a working depth adjustable between 3 and 10 centimetres, making it suitable for a range of soil conditions and crop requirements. The harrow is equipped with 72 inclined discs arranged in two rows, each disc measuring 510 × 6 millimetres with a spacing of 246 millimetres between discs within each row. The discs are serrated to enhance cutting and mixing action. Each disc is supported by four elastomer shock blocks to reduce vibration and extend disc life, whilst tapered roller bearings requiring no maintenance provide reliable operation under field conditions.
The machine incorporates a double U-profile roller weighing 175 kilogrammes per metre to consolidate and level worked soil, and lateral deflectors to contain soil movement within the working path. Support wheels measuring 400/60 × 15.5 inches at the front, fitted with hydraulic depth and height adjustment, allow precise control during operation. The harrow is towed via a drawbar with a 71-millimetre coupling eye and is equipped with two 560/60 R 22.5 transport wheels and a pneumatic braking system. A covering harrow is included to smooth the final seedbed.
The transport width is 3 metres with a folding frame for road travel. The approximate operating weight is 9,150 kilograms. Recommended working speed ranges from 7 to 15 kilometres per hour, with a power requirement between 270 and 450 horsepower depending on soil conditions and depth of operation. The machine is currently located in Timișoara, Romania, and was manufactured in 2021.
