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.

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.

A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.

A variable rate air metering system is provided. The system includes seed meter cartridges, each having a housing, a meter wheel, and a variable speed electric motor operatively connected to the seed meter cartridge. The seed meter cartridges provide flowable material to distribution manifolds, which are configured to distribute flowable material to multiple row outputs for deposition into a field. A control system is configured to control operation of the distribution manifolds for enabling/disabling dispersement of flowable material to row units. The control system is also configured to adjust the dispersement rate of flowable material by the seed meter cartridges in association with the opening/disabling the dispersement of flowable material to row outputs.

The work vehicle has a venturi structure with a plurality of venturi tubes that are disposed in a compact arrangement.

A metering device for an agricultural machine for outputting granular solids out of at least one storage container to at least one dispensing unit by means of, in particular, a pneumatic conveyor system, has a metering housing. The metering housing comprises at least one mounting flange on the storage container-side and/or conveyor system-side as well as at least one inflow opening and at least one discharge opening for the granular solid. The at least one mounting flange is formed as polygon or circular.

An agricultural metering system includes a modular meter roller cartridge. The modular meter roller cartridge includes a meter roller. The modular meter roller cartridge further includes a housing rotatably supporting the meter roller. The housing is configured to selectively engage a meter box of the agricultural metering system to support the meter roller within the meter box while the housing is engaged with the meter box, and to selectively disengage the meter box.

A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.

A row unit of an agricultural planter includes a seed meter. The seed meter includes a seed disk within a seed meter housing. The seed disk is positioned in the seed meter housing such that the disk rotates and includes a seed release point. A drive member is operatively connected to the seed disk such that the drive member selectively rotates the disk. The seed disk is angularly positioned and is a conical-shaped member with a central axis and includes seed cells radially positioned about an outer portion. The seed disk is substantially non-perpendicular to the central axis. An air pressure source also is included to adhere seed to the disk.
