Locations of seeds in a field can be identified. A material is applied to the field by an agricultural machine, based upon the seed locations. The placement of the material is detected and the agricultural machine is controlled.

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.

An example seed double eliminator includes a base, an arm pivotably coupled to the base and pivotable about a first axis, and a rotatable wheel rotatably coupled to the arm. The arm may be biased in a direction away from the base. The wheel may be rotatable about a second axis. The wheel may include an exterior surface configured to unsettle a seed maintained at a location along a seed disc to remove the seed from the location.

Seed capture devices for a seed meter may include a seed a movable element configured to capture seeds from a seed disk of a seed meter and a power transmission element operably coupled to the movable element to drive the movable element when the seed meter is in operation and operably coupled to a mechanical contact element of the seed disk of the seed meter to drive the power transmission element when the seed meter is in operation.

A planting unit for a seeding machine having a frame member and a seed meter mounted thereto. The seed meter has a housing and a metering member rotatably mounted therein. The metering member has a sidewall with an inner surface and an outer surface with a rim portion of the sidewall adjacent an outer edge of the sidewall. The inner surface of the side wall and the housing form a trough at a bottom portion of the metering member to hold a seed pool. A mechanical seed delivery system takes seed from the metering member and moves seed to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine.

A distribution assembly for distributing a granular product that are to be distributed on the ground comprises, a mechanism for distributing granular product singly, a mechanism for conveying singled granular product to the ground, and a mechanism for transferring the singled granular product from the mechanism for distributing to the mechanism for conveying. The mechanism for transferring may be synchronized in terms of speed and in terms of position with the mechanism for distributing, and the mechanism for transferring may capture the granular product singly and immobilize it within the mechanism for transferring, so as to keep each granular product spaced a determined and constant distance from one another, in the mechanism for transferring and during the transfer of the granular product to the mechanism for conveying.

A separating device for a distribution unit of granular elements counting a plurality of perforations each including an internal channel with an inlet and an outlet, including an separating wheel including a rotation axis and a peripheral surface, the separating wheel including a plurality of radial projections projecting from the peripheral surface, which are designed to be inserted into the internal channel of one of the perforations in an insertion position, wherein the radial projections are designed to be inserted through the inlet of the internal channel of one of the perforations in a sealing manner inside the internal channel by shape matching and/or by a sealing element in the insertion position so as to achieve sealing inside the internal channel.

A seed-delivery device having a seed meter (128, 328) having a metering disc (202) configured to receive seeds, a seed tube (130, 330) coupled to the seed meter (128, 328), and a seed accelerator (200, 300) having an air inlet and a conduit, the conduit directing an air flow from the air inlet to the seed tube (130, 330) in a direction away from the seed meter (128, 328), the air flow configured to entrain and accelerate a seed in a direction away from the seed meter (128, 328) as the seed passes through the seed tube (130, 330).
