A seeding apparatus includes an implement frame mounted on wheels and a plurality of furrow openers mounted on the implement frame. A primary air seeder cart is pivotally connected about a vertical implement pivot axis to an implement hitch on the implement frame, and an implement pivot limiting system is operative to limit a degree of pivoting of the primary air seeder cart about the implement pivot axis with respect to the implement frame to a selected degree chosen to reduce bending of conduits. A secondary air seeder cart can be pivotally connected to a cart hitch on the primary air seeder cart about a vertical cart pivot axis and an cart pivot limiting system is operative to limit the degree of pivoting of the secondary air seeder cart about the cart pivot axis.

A bearing end cap for a modular meter assembly for distributing particulate material from an applicator can include recesses that accommodate locking tabs or fingers of modular meter unit housings and protrusions that lock a meter tube against rotation. In one aspect, a bearing end cap can be provided with a particular construction that cooperates with modular meter unit housings. The bearing end cap can have vertical and horizontal symmetry and cutouts near its corners. These cutouts can provide clearances to accommodate the locking tabs or fingers of modular meter unit housing end walls. Back walls of the bearing end caps can have protrusions that extend into end cutouts of a tube which defines an interior perimeter of the meter assembly.

A tubular sleeve for a modular meter system for distributing particulate material from an applicator can be inserted through a meter assembly that is built from modular meter unit housings to define the boundary wall of a meter cavity and provide internal structural support for the meter assembly. The tube can be provided with inlet and outlet openings that can be inserted through modular meter housings to form an overall meter assembly of a particular length and therefore volume/flow rate. In one aspect, a tube or tubular sleeve can be inserted into a stack of connected meter units while assembling a modular meter assembly. A circumferential sidewall of the tube can have pairs of oppositely positioned openings that provide inlets and outlets for a meter assembly.

An improved particulate metering system is provided. The system includes an air flow origin and a plurality of particulate accelerators. A single particulate source is in communication with the particulate accelerators. Each of a plurality of operated conveyances can be in operable communication with the single particulate source and one of the particulate accelerators. The system includes a confluence of the air flow and the particulate within the mixing area of each of the particulate accelerators. Each of a plurality of discharges can be associated with the particulate accelerators. The operated conveyances can operate at different rates. The system can include one or more gearboxes adapted to be inverted and controlled by a second drive system. The improved system and controls provide variable application rates of particulate across rows in a field.

Device for delivering solid particles on demand, intended for agricultural machine, wherein the delivery on demand of solid particles to a receiving device is regulated, particularly in the field of technology for transporting solid granulated materials by means of an air stream, without being exclusive, in agricultural machinery when an air stream is used to transport seeds or fertilizer granules from at least one central hopper to the dosing/metering equipment located on the sowing unit, and including a source of pressurized air, a distributor of solid particles “S”, a hopper whose bottom feeds solid particles “S” to the distributor and a plate permeable to the passage of air and on which said particles “S” settle.

A planter includes a seed a delivery system for delivering seed from one or more hoppers to one or more row units of the planter. The seed delivery system includes a number of seed entrainers. The seed entrainers receive seed from the one or more hoppers. The seed is combined with a fluid, such as air, which moves the seed through the seed entrainer and towards one or more row units of the planter. The entrainer includes one or more outlets, with the outlets corresponding to different row units, and the outlets can be varied based upon the need of seed delivery for the planter.

Various methods, systems, and devices for flexible and accurate seed spacing control in a seed planting system. The various embodiments receive singulated seed from a metering device and control movement of the seed toward a seed spacing device that receives the seed. The seed spacing device, which is disposed near the soil surface, independently controls the ejection of the seed from the device and thus the spacing of the seed in the furrow.

An inductor apparatus includes an inductor assembly mounted under a seed container such that seeds flow into a reservoir. An air conduit carrying pressurized air extends along the reservoir. Seed channels extend from an inlet located above a pickup air opening in the air conduit to an outlet, and a bypass channel extends downward from each seed channel through an upper wall of the air conduit. A pickup air stream flowing out the pickup air opening forms a seed air stream entrained with seeds flowing into each seed channel inlet and a bypass air stream flows from the air conduit through each bypass channel into each seed channel and the combined seed and bypass air streams flow out the seed channel outlets. The seed channel outlets can be arranged along each side of the inductor assembly, and the rate of flow of the bypass air stream can be adjusted.

A particulate material agitation and leveling system includes a controller having a memory and a processor. The processor is configured to receive a sensor signal indicative of a measured weight distribution of a particulate material within a storage tank of an agricultural system, determine whether a determined variation between the measured weight distribution and a target weight distribution is greater than a threshold variation, and control an agitator to decrease the determined variation in response to determining that the determined variation is greater than the threshold variation.
