Abstract
Agricultural implements are used to transport material, such as inputs in the form of fertilizer, seed, treatment, or some combination thereof, to row units that apply the material to an area of a field. Metering systems can aid in metering and providing a desired amount of material, such as on-demand, to the row units. The metering systems move the metered material to the row units, such as with pneumatics or other fluids. The metering system can be improved by having primary and secondary nozzles of different sizes, which aid in increasing the speed of the fluid moving the material towards the row units. For example, a smaller diameter for the secondary nozzle will provide improved suction and air speed.
