ABSTRACT:
A precision-type single-seed planter has seed distributor in the form of a disk provided with elongate perforations of a narrow width, which cooperate with a seed container and an air suction device. Because the perforations in the disk have an elongate shape and a small cross section even large seeds can be held on the disk by suction at each of the perforations whereas smaller seeds will also be held without being able to pass through the perforations. A selector element cooperates with the disk by throttling the suction effected on the seeds through the perforations so that only individual ones of the seeds, particularly the smaller seeds, are adhered at each perforation. An optimum seed separation and single-seed distribution effect is thus achieved, regardless of the size and shape of the seeds.
