A working element for broadcasting mineral fertilizers includes a disk, the surface of which is divided into sectors with different central angles, and in each of the sectors guiding ribs are disposed one by one, the radii of which do not coincide. The surfaces of blades and guiding ribs are covered with a layer of polymer material, for example Capron, having good adhesion with the surface and reducing the friction coefficient between the working surfaces and particles of mineral fertilizers. |
