Metering device for an agricultural implement are present for applying a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.

An engine is operated to produce exhaust emissions containing carbon nano soot therein which are injected into a solubilizing tank containing nitic acid and carbonic acid in a water solution for solubilizing the carbon nano soot as carbon nano tubes. A gas flow exiting the tank is captured such that some water and some solubilized carbon nano tubes are carried with the gas flow for subsequent delivery to a plant growing medium, either directly or by storing the water and solubilized carbon nano tubes carried with the gas flow in a tank for subsequent application. The solubilizing tank may be supported on agricultural seeding implements or sprayer implements for direct application to crop covered ground. In an irrigation system, the gas flow from the solubilizing tank is directed towards a condensing tank for subsequent application of the condensate to a plant growing medium with irrigation water.

A sectional control device controls the flow of particulate material from a meter assembly to a primary manifold of an air seeding system. The sectional control device includes a plate assembly having particulate openings extending between the meter assembly and the primary manifold and a shut-off mechanism configured to control the flow of the particulate material through the particulate openings. The shut-off mechanism includes a gate configured to slide between an open position, where particulate material can flow through the particulate opening, and a closed position, where particulate material is prevented from flowing through the particulate opening. The shut-off mechanism also includes an actuator configured to drive the gate between the open position and the closed position.

A method including adjusting a changeable component of a seed planting machine when switching from a first variety of seed to a second variety of seed during planting, wherein the adjusting is based on a location of the planting machine.

A device for performing autonomous agricultural operations may include a toolbar to which a plurality of implements may be interchangeably coupled, and a pair of parallel chassis beams mounted perpendicularly on the toolbar. At least a portion of each of the chassis beams may be telescopic and configured to be extended outward from, and retracted inward towards, the toolbar. The device may also include a plurality of drive assemblies each mounted on one of the chassis beams, and a plurality of motors corresponding to the drive assemblies and configured to drive the drive assemblies in accordance with one or more drive parameters to move the device throughout a site. The device may further include a computing device configured to automatically determine the drive parameters, and cause the plurality of motors to drive the corresponding drive assemblies in accordance with the drive parameters.

A meter roller for an agricultural metering system includes a flute and a recess positioned adjacent to one another along a circumferential axis of the meter roller. The flute and the recess are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller. In addition, a first circumferential extent of the flute is at least 1.5 times greater than a second circumferential extent of the recess along an entire longitudinal extent of the flute and the recess, and the entire longitudinal extent of the flute and the recess is greater than the first circumferential extent of the flute and the second circumferential extent of the recess.

An agricultural planting implement is used to plant seed in a field. The implement includes an electrically-driven seed meter that is spaced on a toolbar of the implement. The seed meter, or other metering member, is a precision meter that is used to control the volume, spacing, and location of a seed that is delivered from a meter to the field. A seed source, such as a seed cart or hopper, is attached to the seed meters to provide an on-demand amount of seed to the meters for planting in the field.

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, 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 feeding device, and the energy to the fertilizer supply device.
