We have several Koppert sowing machines (Occasion), such as the Profi, a machine made of stainless steel with a very solid design, specially developed and suitable for growing seedlings. The Koppert Profi sowing machine is driven by the tractor and the sowing shaft is driven by an electric motor to prevent any slippage. All the sowing elements are mounted on a fixed frame because all the seeds are also sown at the same depth; This is necessary for uniform growth.

In the tractor cabin, it is possible to connect and disconnect the sowing distance, the seeds used, the amount of seeds per square meter from a screen. Tread wheels can be manufactured as cage wheel or SS roller models depending on the type of soil, light or heavy. When sowing, the machine draws a "furrow" in the soil into which the seeds fall. Then they are covered again by the rear roller. Seed distance, row width and seed depth are fully adjustable with this machine. The minimum row width is 5,5 cm and the distance from the seed can be set from 1mm to 15cm. The machine is delivered with a width of 1,20 m or 1,40 m.
