A disk-type planting unit consists of a solid disk, two pressure plates and stuck-open grippers which are arranged in the staggered order on the both sides of the disk. On each of the grippers at the preset angle as regards to a disk radius stop pins are mounted. On each of the pressure plates an orientating unit is disposed. It consists of a control plate, which is arranged at angle of setting the stop pins, and on which a spring is mounted, the tension of which is adjusted by a nut bolt, and on the disk and spring, in the area of plant contact, a polymer coating is applied. |
