KUHN Farm Machinery has expanded its range of minimum tillage seed drills with a 4-metre foldable version of its Espro. In common with its larger 6m (6000 R) sibling, the 4000 R uses two rows of cultivating discs followed by a single row of large diameter and offset (900mm) wheels. The newcomer also uses the company’s Crossflex coulter bar; each coulter is mounted on polyurethane blocks which allow the individual coulters to follow terrain contours. This, says Kuhn, ensures a consistent seeding depth across the full working width and, in turn, results in homogenous seedling emergence. Power requirement starts from as low as 140hp, and the manufacturer claims high drilling speeds and says the 4000 R is compatible with a wide variety of seed types and sizes. All settings, such as seeding rate, drilling depth and tamping pressure, are altered via a VT50 or CCI200 ISOBUS control terminal. The same terminal also operates the machine’s automated headland turn function. Optional equipment includes front press wheels – with in-cab pressure adjustment – to pre-level the land in front of the working discs and to prevent the machine from sinking into lighter or wet soils.
