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.

A metering system for an agricultural vehicle includes meter rollers, each including protrusions driving flow of flowable particulate material in response to rotation of the meter roller. The metering system also includes a drive shaft driven in rotation and includes transmission assemblies that each correspond to a respective meter roller. Each transmission assembly includes a respective moveable gear actuatable to engage each of a plurality of gears to establish a respective gear ratio corresponding to one of a plurality of different speeds of the respective meter roller relative to the drive shaft.

A dual-impeller spreader capable of independently a flowrate of particulate material about two halves of the spreader's coverage area. The spreader includes a frame, a hopper, and wheels rotatably connected to the frame via an axle. A first impeller is fixed to a first impeller shaft rotatably coupled to the axle via a first gear train, and a second impeller is fixed to a second impeller shaft rotatably coupled to the axle via a second gear train. A first shut-off control selectively opens and closes a first set of hopper exit openings located above the first impeller, while a second shut-off control selectively opens and closes a second set of hopper exit openings located above the second impeller. The first shut-off control and the second shut-off control selectively open and close the respective openings independent of each other.

An agricultural air cart assembly is provided with individually controlled product distribution lines which allows for balanced pressures and even dispersal of air through different distribution lines of different lengths running to different sections or row units of a seeder or drill. Rotatable fans are operatively connected to corresponding first and second distribution lines and are configured to generate optimized air flows in the first and second distribution lines which entrain and carry the product downstream toward corresponding row units at balances pressures. A controller is operable to adjust the pressures of the air flows outputted by the first and second fans by adjusting the position of corresponding fan shrouds over the intakes of the first and second fans.

Various seed planter embodiments may comprise a frame including a main frame section and a furrowing disk frame section. A plurality of planter assemblies may be connected to the main frame section, and a plurality of furrowing disks may be connected to the furrowing disk frame section. At least one linkage may connect the main frame section and the furrowing disk frame section, and at least one motor may be configured to move the furrowing disk frame section with respect to the main frame section, wherein the at least one linkage permits the furrowing disk frame section to move to a low position for no-till planting and move to a high position for prepared seed beds or conventional planting.

An apparatus and methods for delivering seed from a metering device to a furrow. In one embodiment, a seed meter entrains and releases seed from a seed disc at a seed release location. The released seed is directed into a seed conveyor by a loading wheel. The seed conveyor conveys the seed toward the soil and releases the seed with a rearward relative velocity.

A pneumatic delivery system for particulate agricultural products includes one or more compartment for containing and supplying one or more particulate product. An inductor assembly separately receives and fluidizes the particulate products and conveys the fluidized products to a metering assembly. The metering assembly separately meters each of the product flows and transfers the metered flows to one or more delivery units for applying the products. The pneumatic delivery system can be used on various implements, including planters and applicators for applying seeds, fertilizer, pesticides and other products.

The invention relates to seed material pellets of elongated form each comprising at least two seeds of elongated form, wherein the pellets consist of the seeds embedded within a matrix, wherein at least 80% of the seeds are oriented in directions essentially parallel to the pellets, and wherein the matrix does not comprise distinct layers of different constitution.

An air seeder assembly that has a tank for containing commodity, a meter assembly coupled to the tank and configured to selectively distribute commodity there through, a first conduit coupled to the meter assembly to direct commodity provided to the first conduit from the meter assembly to a tool assembly, a diverter that selectively diverts commodity to the first conduit, and a sensor coupled to the diverter to identify when commodity is passing thereby.
