The invention relates to an agricultural machine called a tetrafunctional subsoiler, for lowland areas or alluvium, which allows four different agricultural tasks to be carried out within the same application. The invention is characterised in that it has a front roller with cutting disks, followed by a set of height-adjustable subsoiling plough arms with interchangeable points, and followed by a smooth flattening metal roller, with prongs, with a seed drill applied to the chassis. |
