A work vehicle includes a delivery system with a run. The runincludes an upstream flow structure having an inlet that isconfigured to receive metered commodity and a suctiongenerator structure with a flow passage that is in fluidcommunication with the inlet. The flow passage includes aventuri profile with a restricting section and an expanding section.Furthermore, the run includes a downstream flow structureconfigured to receive the metered commodity via the flowpassage and an airstream that conveys the metered commodityin a downstream direction through the downstream flowstructure. A compressed air source is configured to providepressurized air through the flow passage to create suction tosuck the metered commodity away from the metering system andtoward the downstream flow structure.
