An air seeding system and method includes a manifold mounted across a plurality of row planter units. Electric motors are mounted on the manifold and are operatively connected to the seed meters. A microprocessor or controller adjusts the speed of the motors in response to field data input so as to adjust the rate of seed dispensement to achieve desired plant population. The motor speeds can be adjusted on the fly, without stopping the air seeder. The system senses ground speed, senses the raised and lowered positioned of the row planter units, and senses any blockage of the row planter units. The motors eliminate the need for a ground drive wheel.

The invention relates to a single seed dispenser (10) for a precision automatic sower comprising a cover (11) for seeds to be distributed joined to a body (12) containing a cavity (24) in communication with an aspirator of the seeds via a conduit (22) inserted in a hole (23) realised on the body (12), a distribution disc (13) with holes (38, 54) contained in a compartment delimited by said body (12) and by said cover (11); a driving disc (31) joined through pins (53) to the distribution disc (13), both discs being put into rotation by means of a shaft (29) actuated by an actuator for commanding rotation of the discs (13, 31); and a selector device (14) for the seeds pivoted on the edge of the body (12), where the selector device (14) comprises a plate (142) which presents, on a side facing the centre of the distribution disc (13), at least two toothed portions (143, 144), having teeth of different sizes and a curved sector (59) mounted against the surface of the distribution disc (13) opposite to the plate (142) and is provided with protrusions (591) having inclined surface (592) facing the distribution disc (13) at holes (38) therein.

A plenum of distributing a flow of air from an air source includes ports extending from a face element of a body. The ports are configured to direct the flow of air out of the plenum, and the ports are arranged on the face element in a first row having first length, a second row having a second length, and a third row having a third length. The first row is positioned proximate to the top element, the third row is positioned proximate to the bottom element, and the second row is positioned between the first row and the third row. In addition, the second length is greater than the first length and the third length, and a shape of the face element is configured to accommodate the first length of the first row, the second length of the second row, and the third length of the third row.

A commodity tank for a product distribution machine has a hollow body enclosing an interior space with an upper fill opening through which product can flow into the interior space. For convenience of the operator, a lower fill opening is also provided though which product can flow into the interior space. The lower fill opening is located at a lower height relative to the upper fill opening. The provision of the lower fill opening enables the operator to choose between either bulk filling the tank using the cart conveyor through the upper opening or manually filling the tank through the lower opening.

A particulate material sensing and agitation control system of an agricultural system having a drive system configured to operate an agitating system, and a controller having a memory and a processor. The controller is configured to receive at least one sensor signal indicative of a profile of a particulate material within the agricultural system, and output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material. The agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, and the plurality of operating modes includes an agitation mode and a leveling mode.

An agricultural implement system is provided including a fluid conduit configured to provide product to a ground engaging tool. The ground engaging tool is configured to deposit the product into soil. The agricultural implement system also includes an air source fluidly coupled to the fluid conduit, and configured to provide an air flow through the fluid conduit in a downstream direction toward the ground engaging tool. The agricultural implement system further includes a product delivery system fluidly coupled to the fluid conduit, and configured to transfer the product into the air flow. In addition, the agricultural implement system includes a product flow measurement system configured to determine a mass flow rate of the product based on a pressure drop between an upstream portion of the fluid conduit and a downstream portion of the fluid conduit, a flow rate of the air flow, and a velocity of the air flow.

A product distribution system for an air seeder includes a plurality of furrow openers and a plurality of product distributors mounted on an implement frame. Each product distributor comprises a seed container and a plurality of seed delivery conduits extending radially outward from the seed container A seed meter apparatus is connected to receive the seed product from the seed container and operative to meter seeds of the seed product into each of the seed delivery conduits. A seed product dispenser is operative to convey a seed product from a seed product tank into each seed container, and is operative to maintain a level of the seed product in each seed container above a selected level. The product distributors are spaced across the width of the implement frame.

A biasing system is provided for use with an associated run selector device having a valve body member movable within a housing between opposite first and second run selection positions selecting respective first and second commodity distribution runs of the associated run selector device. The biasing system includes a first biasing element on the housing, and a second biasing element on the valve body member. The first and second biasing elements are movable relative to each other between opposite first and second biasing system positions together with the associated valve body member being moved relative to the housing between the opposite first and second run selection positions. The first and second biasing elements are mutually biased against each other to urge each other apart and towards a one or the other of the opposite first and second biasing system positions.

A seed meter is provided for planting multiple types of seed and rapidly switching between the types being planted in a single planting pass of a planting session of row-crop planting. The seed meter has a segmented seed meter reservoir with multiple seed meter chambers arranged between two pairs of seed disks that may be better parallel to each other or angled with respect to each other to define an X-shaped arrangement of the seed disks in the seed meter. Activation and deactivation of the seed disks within the seed meter are synchronized to selectively deliver a single one of the multiple types of seed from the respective seed meter chamber for delivery out of a single seed tube of the seed meter, which may provide absolute and instantaneous on-the-go seed switching within a single row from each seed meter.

An agricultural product distribution apparatus includes a primary product container mounted on a product cart and a secondary product container. A metering device and a primary inductor assembly are mounted to the primary product container and a control system controls dispensing of products from the primary product container either through the metering device directly to furrow openers, or through the inductor assembly to the secondary product container and then through a secondary inductor assembly to downstream singulating meters. The secondary product container can be mounted on the implement frame or the product cart. A plurality of primary product containers can be mounted on the product cart each with a metering device and primary inductor assembly such that each tank can dispense through either of the corresponding metering devices or primary inductor assemblies.
