A meter has a meter inlet at the outlet of the commodity tank, a meter outlet, and a metering device between the meter inlet and the meter outlet. A manifold has a commodity inlet at the meter outlet, a first shoot having a first air inlet and a first manifold outlet, and a second shoot having a second air inlet and a second manifold outlet. A valve is positioned upstream of the first and second air inlets and configured to selectively direct an airflow to the first air inlet and to selectively direct the airflow to the second air inlet. Each of the first shoot and the second shoot are in selective communication with the commodity inlet to receive the commodity therefrom.

Abstract: An example agricultural machine comprises a material distribution system that includes a material distribution line configured to convey particulate material to a component. The agricultural machine comprises a sensing system that includes a first sensor configured to generate a first sensor signal indicative of a measure of a flow of the particulate material in the material distribution line, a second sensor configured to generate a second sensor signal indicative of a measure of the flow of the particulate material in the material distribution line, and a correlation generation component configured to receive indications of the first and second sensor signals and to generate a correlation metric that represents a correlation between the first and second sensor signals. In one example, the correlation metric is applied to a sensor signal from a second material distribution line to determine a flow rate in the second material distribution line.

Abstract: A closure assembly is disclosed for a work machine having a supply tank with a tank opening. The closure assembly has a lid and lift, actuator and latch mechanisms. When the closure assembly is attached to the tank, the lift mechanism is configured to support the lid off of the tank opening. The actuator mechanism mounts to the lid to move the lid with respect to the tank opening between first and second positions in which in the first position the lid overlies the tank opening and in the second position the lid is substantially clear of the tank opening. The latch mechanism may be moved into a latched orientation in which when the lid is in the first position the latch mechanism latches the lid into engagement with the tank opening.

Abstract: A seeding system includes a commodity tank configured to store a commodity. The commodity tank has a first outlet and a second outlet. A volumetric meter has a meter inlet at the first outlet of the commodity tank, a meter outlet, and a metering device between the meter inlet and the meter outlet. A manifold has a commodity inlet at the outlet of the volumetric meter, an air inlet, and a manifold outlet. A first dispersion device has a plurality of outlets and an inlet in communication with the manifold outlet. A second dispersion device has a plurality of outlets and an inlet in communication with the second outlet of the commodity tank. The second outlet of the commodity tank bypasses the volumetric meter.

Abstract: A product distribution system includes a product on demand pick-up assembly including a hopper. The hopper is configured such that an air stream flowing into the pick-up assembly entrains product therein and conveys product downstream through a plurality of conduits. The product distribution system further includes a container for storing product prior to delivery of product to the pick-up assembly and a meter and conveyor assembly configured to move product from the container to the pick-up assembly hopper such that an amount of product greater than a predetermined quantity is maintained in the pick-up assembly hopper during operation of the system.

Abstract: A data processor retrieves or accesses a reference bin level versus reference phase for a determined seed type. A measurement device, receiver, or phase measurement module measures an observed phase of a primary received signal. The data processor is adapted to determine an estimated bin level of seeds, where the estimated bin level is established as the reference bin level that corresponds to a respective reference phase that is closest in value to the observed phase.

Abstract: A closure arrangement for a tank includes a tank lid and an opening flange. The opening flange has first and second tank flange lips spaced by an offset distance. The tank flange lips extend toward one side of the tank. The tank has a lid flange with first and second lid lips spaced by an offset distance corresponding to the offset distance. The lid lips extend, at least in part, toward a second side of the tank. The lid lips include first and second walls arranged at a tank interior side of the respective first and second tank flange lips in an offset direction. When the tank lid is closed over the tank opening, one or more seals engage the tank flange lips from the tank interior side and engage the lid lip walls of the lid flange from an exterior side of the tank in the offset direction.

Abstract: In a method of operating a seed cart, a compartment is provided defining a volume for receiving a commodity. A distribution manifold is provided including two sets of passages, the distribution manifold being associated with the compartment to selectively receive a commodity in one or both of the two sets of passages. A fan is operated to create an air stream. The air stream from the fan is divided into a plurality of primary tubes. An inlet divider plenum is provided having two outlets in communication with each one of the primary tubes. The flow of air from each of the plurality of primary tubes is divided amongst the two corresponding outlets with a corresponding movable vane within the inlet divider plenum such that an airflow ratio between the two sets of passages is controlled in response to the position of the vane.
