  • Agricultural seeding system
    Patent number: 7717048
    Abstract: A seeding machine having at least one tool bar, a plurality of row units and a processing circuit. Each of the plurality of row units are connected to the toolbar. Each of the row units have a seed metering device, a seed placement device and a seed sensor. The seed metering device includes a seed disk providing a metering action to a plurality of seeds. The seed placement device receives the seeds from the seed metering device. The seed sensor is positioned to detect the passage of seeds through either the metering device or the seed placement device. The seed sensor producing a signal indicative of the passage of the seeds. The processing circuit is receptive of the signal from each of the seed sensors of each of the plurality of row units. The processing circuit determines a seed placement parameter dependent upon the signal, the processing circuit alters the metering action of the seeds dependent on the seed placement parameter.

  • Seed metering system for use in a seeding machine
    Patent number: 6752095
    Abstract: A seeding machine includes at least one seed metering system and at least one seed placement system. Each seed metering system includes a seed disc having a plurality of spaced apart seed cells and a circumferential edge. An edge drive engages the circumferential edge for rotatably driving the seed disc. Each seed placement system is in communication with a corresponding seed metering system.
