    Abstract: An agricultural planting implement includes a number of row units. The row units include one or more seed meters for receiving, singulating, and dispensing seed to the ground such that preferred spacing of subsequent seed is attained. A seed meter provides seeds one at time to a seed carrier, such as a brush wheel. The brush wheel may move the seeds one at a time to a seed conveyor by directly moving seeds along a curved portion of a seed disc in the seed meter. The seed conveyor may be a flighted belt, and the velocity of the seeds when transferred from the seed carrier may match the velocity of the flighted belt. The seed conveyor conveys the seeds to a position near the bottom of a furrow, and ejects the seeds with little or no horizontal velocity relative to the bottom of the furrow.

    Abstract: An agricultural implement is provided that includes a number of row units. The row units include one or more seed meters for receiving, singulating, and dispensing seed to the ground such that preferred spacing of subsequent seed is attained. Seed delivery systems are included to aid in transporting the seed from the seed meter to the ground in a controlled manner to mitigate skips and to aid in controlling the spacing of the seeds, which can be based upon the ground speed of the implement as it moves through the field. The seed delivery systems can control the transport of the seed to a furrow in the field such that the seed can experience zero or near zero relative velocity so that the seed will have little to no movement once positioned in the furrow.

    Abstract: An agricultural planter includes a plurality of row units attached to a toolbar. The row units include seed meters in seed meter housings for receiving, singulating, and dispensing seed or other particulate. The seed meters include a circular seed disc with a seed path for receiving the seed in the seed meter housing. Integrated with the seed meter, such as at the housing, is an electric pressure source dedicated for providing a pressure differential for the seed meter or meters at a particular location on the planter. The pressure source can be positive or negative to temporarily adhere seed to the seed disc of the meter. A single pressure source can provide the pressure differential to a single meter or to multiple meters or discs at a row unit.
