  • Patent number: 10999966
    Abstract: A pneumatic seed delivery system is provided for use with planter for row-crop planting an agricultural field in which the pneumatic seed delivery system may use high pressure air to accelerate seeds that are singulated from a seed meter to match ground speed when planting. The pneumatic seed delivery system includes an air accelerator arranged downstream of a release location of the seed meter. The air accelerator may define a pneumatic device such as an air conveyor or air amplifier that merges a primary airflow with a controllable supplemental airflow to provide a correspondingly controllable combined airflow that carries and accelerates the singulated seeds so that the seeds can be released with a rearward horizontal seed velocity component that approximates a forward ground speed of the planter to reduce seed tumble.
