Abstract
A precision seeder for sowing seeds to obtain a predetermined number of plants per unit of length includes a seed discharging tube adapted to feed the seed by an excess air pressure from a seed distributing device to a seed outlet, a seed furrow opener including two sowing discs arranged at an angle relative to each other, and a resilient press surface for pressing the seed into the soil. The press surface is configured such that a direction of flow of the seeds at the seed outlet intersects or is substantially tangent to at least a portion of the press surface. The seed outlet is located between the sowing discs and, as seen in the transverse direction, inside or immediately adjacent to the periphery of at least one of the sowing discs.

31. A method for precision sowing of seeds to obtain a predetermined number of plants per unit of length, comprising:
-
feeding single seeds from a seed hopper by a seed distributing device; feeding the seed by an excess air pressure via a seed discharging tube from the seed distributing device to a seed outlet; opening a seed furrow by a seed furrow opener, comprising two sowing discs arranged at an angle relative to each other; and pressing the seed into the soil by a resilient press surface, wherein the seeds are fed through the seed outlet such that a direction of flow of the seed at the seed outlet intersects or is substantially tangent to at least a portion of the press surface; and the seeds are discharged from the seed outlet at a position between the sowing discs and, as seen in the transverse direction, inside or immediately adjacent to the periphery of at least one of the sowing discs. - View Dependent Claims (32)
