A Kuhn Optimer L400 is a three-point mounted disc harrow, a primary and secondary tillage machine designed to break up, mix, and level soil following harvest. Kuhn is a recognised European manufacturer of agricultural machinery serving cultivation, hay-making, and forage systems across smallholder and commercial farm operations.
This 2022 unit is equipped with 32 convex and notched discs, each 510 mm in diameter and 6 mm thick, arranged individually on suspension arms to follow ground contours independently. The working width is a rigid 4.00 metres. Notched disc geometry promotes soil crumbling and effective mixing, particularly suited to light and medium-weight soils. Working depth ranges from 3 to 10 centimetres and is controlled hydraulically via a stepless adjustment system, fitted with a large depth-scale dial for operator reference.
The harrow is rated for tractors between 120 and 200 horsepower and attaches via Category III and IV lower-link couplers. Ground clearance beneath the disc carriers reaches 55 centimetres, allowing operation through heavy crop residue volumes without blockage. A Flexliner roller of 540 mm diameter provides depth guidance for consistent, shallow working and soil re-consolidation. Two side-boundary discs are fitted and foldable for transport. Overload protection is furnished by four polyurethane elastomer blocks, and bearings are double-row angular-contact units with lifetime grease filling.
The machine incorporates road lighting and warning reflector panels. Its compact frame geometry places the centre of gravity near the tractor, improving handling and stability. Soil throughput and crumble quality remain good even at shallow working depths.
The machine is located in Germany (D-91448 Emskirchen-Mausdorf) and is priced at $18,921. Serial number KHUA1061H00A00132; year of manufacture 2022.
