Patent attributes
A planting unit for a seeding machine comprising a seed supply, a seed meter and a seed delivery system to deposit the seed within a furrow. The seed meter is driven by an electronic control unit to achieve a pre-defined pattern of the seeds. The planting unit is adapted to skip dispensing of seeds at locations at which a tramline extends transversely to the travel direction. The following possibilities to achieve the tramline are described: (a) the seed meter comprises adjacent apertures for receiving the seeds and at least one of the apertures is closed, (b) a seed branch-off assembly is adapted to take a seed out of the seed delivery system, (c) the seed delivery system is slowed down to reduce the speed of the seed transport, (d) a seed transport device for moving a seed from the seed meter to the seed delivery system is disabled, or (e) a seed removal device is provided to provide the skip.
