Systems, methods, and apparatuses for calibrating a first meter of an air cart include determining a calibration factor using a second meter. The second meter may be located with the air cart or remotely from the air cart. An amount of material dispensed from the second meter is used to determine the calibration factor. A number of cycles of operation of the second meter may also be used to determine the calibration factor. The calibration factor may be provided via a wired or wireless connection to a controller operable to control operation of the first meter.

An air manifold system for supplying an agricultural product to a plurality of metering devices comprises a product hopper having a product flow cavity, the product cavity separated from a first plenum by an air agitator sandwiched between the first plenum and the product flow cavity. The hopper comprises a plurality of nozzles extending through a wall of the hopper. A venturi assembly is in fluid communication with at least one nozzle. A first forced air stream flows through the first plenum and the air agitator into the product flow cavity to agitate and entrain agricultural product in the first air stream, and the first air stream carries the entrained agricultural product into the nozzles. A second forced air stream flows through the venturi assembly to accelerate the first air stream and the entrained product towards and through the supply hoses connected to the nozzles.

A spreading machine, in particular a precision seed drill, includes at least one seed hopper, at least one fertilizer tank, and a several spreading units. Each of the spreading units includes at least one pneumatically operated separating device to or from which a separation air flow is suppliable or dischargeable and a fertilizer application device. The spreading machine includes a conveying air-driven seed feeding device for providing seed from the seed hopper to the spreading units, and an energy-powered fertilizer supply device for providing fertilizer to the fertilizer application devices. To refine a spreading machine that includes a plurality of consumers, it is provided that the spreading machine includes at least two separate energy suppliers, in particular blowers or pumps, for providing the separation air flows to the separating devices, the conveying air to the seed device, and the energy to the fertilizer supply device.

A flow splitter includes a body having a generally cylindrical main passage therethrough oriented along a longitudinal axis of the body. The main passage connects an inlet at the upstream end to exactly three split passages adjacent the downstream end, each split passage connected to a corresponding outlet. A first and second of the three split passages are oriented along axes that intersect one another at a first acute angle in a common plane with the longitudinal axis. A third of the three split passages intersects the common plane at a second acute angle. An agricultural implement includes a frame, a toolbar carried by the frame and supporting a plurality of row units, a hopper carried by the frame, a primary flow line connecting the hopper to a flow splitter, and three secondary flow lines connecting the flow splitter to three of the row units.

A seed filling system is mounted to a trailing implement that is towed by an agricultural the machine. The seed filling system has a reduced-volume receptacle for receiving seed and a metering assembly that causes the distribution of the seed through a manifold to respective storage containers of plural row units before the seed is dispensed to soil.

Sowing element for precision agricultural seeders comprising a device for selecting the seed, of the type which is formed of a perforated disc having opposing faces that are subject to a pressure differential and a pressurisation device associated with the disc for applying the pressure differential to the faces of the disc, the pressurisation device including a pressurisation bell combined with the disc so as to pneumatically couple thereto in order to guarantee said pressure differential, wherein the bell is rotatably idle with respect to the disc.

The invention relates to a device for metering a granular or grainy material in a distributor machine, comprising a housing; an inlet opening which is formed on the housing and through which a granular or grainy material can be introduced in the housing for metering; an outlet opening which is formed on the housing and through which the granular or grainy material can be discharged out of the housing after metering; a metering space which is formed in the housing in such a way that granular or grainy material in the housing can be moved from the inlet opening via the metering space to the outlet opening; a metering wheel which is arranged in the metering space on a drive shaft, and which is configured to meter the granular or grainy material supplied via the inlet opening; a mounting opening which is formed on the housing and via which the metering wheel can be exchangeably mounted in the metering space; and a mounting component which is detachably arranged in the mounting opening in a mounted position, and this in turn is arranged at least partially welded onto the housing, wherein the mounting component has a receiving unit for detachably receiving the metering wheel, in such a way that the metering wheel received on the receiving unit is mounted on the drive shaft when arranging the mounting component in the mounted position, and in such a way that, when detaching the mounting component from the mounted position, the metering wheel is forcibly detached from the drive shaft (6), such that the metering wheel can be removed from the metering space in this way and can be detached from the housing together with the mounting component. A distributor machine is also provided for distributing a granular or grainy material, such as seeds, fertiliser or grit.

A work vehicle with a metering system, airflow system, and a covering structure moveable between various positions for user access includes features that facilitate assembly and/or disassembly of the metering system. The work vehicle has a venturi structure with a plurality of venturi tubes that are disposed in a compact arrangement.

An agricultural row cleaner having: a frame; a first row cleaner wheel disposed on a first side of the frame; a second row cleaner wheel disposed on a second side of the frame; and a row cleaner diverter connected to the frame and disposed forward of the first row cleaner wheel and the second row cleaner wheel in a direction of travel and disposed between the first row cleaner wheel and the second row cleaner wheel.

An air cart for use in an agricultural air seeding system includes a first storage compartment for holding a first granular product type. The air cart also includes a second storage compartment for holding a second granular product type different from the first granular product type. The air cart further includes a common conduit configured to receive the first granular product type from the first storage compartment and the second granular product type from the second storage compartment to enable simultaneous flow of the first granular product type and the second granular product type. The air cart even further includes a multi-product particle flow rate sensing system configured to monitor respective flow rates for both the first granular product type and the second granular product type during simultaneous flow of the first granular product type and the second granular product type through the common conduit.
