  • Publication number: 20150305230
    Abstract: A pneumatic distribution system for an agricultural implement includes an inductor box having output ports and row units configured to receive an agricultural product and airflow from the output ports. A conduit system extends between the output ports of the inductor box and the row units. The conduit system is configured to direct the agricultural product and the airflow from each output port to a respective row unit. The conduit system includes a first conduit assembly extending between a first output port and a first row unit. The conduit system also includes a second conduit assembly extending between a second output port and a second row unit. A first average diameter of the first conduit assembly is smaller than a second average diameter of the second conduit assembly by at least approximately one percent.
