US Patent 11974517 Agricultural seed detection and tracking system

An agricultural machine includes a seeding system having a seed meter configured to meter seed, a seed meter sensor configured to generate a sensor signal indicative of movement of the seed meter, and an assistive seed transport mechanism configured to receive the metered seed from the seed meter and to transport the metered seed along a delivery path. A control system is configured to determine a position of the seed in the assistive seed transport mechanism based on the sensor signal, and generate a control signal to control the agricultural machine based on the determined position of the seed.
