Abstract

Abstract A system is provided for delivering particulate material from a material storage hopper to a remote discharge station on a wheeled frame structure of an agricultural implement. The system includes a material dispensing mechanism, a connector, and an elongated material conveying tube. The dispensing mechanism is adapted to receive material from the hopper and dispense the material through an outlet conduit. The outlet conduit is directed at an angle relative to the discharge station. The conveying tube delivers material from the dispensing mechanism to the discharge station. The connector interconnects the outlet conduit to one end of the tube and has a passageway therethrough to allow material to pass from the outlet conduit to the tube. The connector is configured to direct the axis of the tube generally closer to the discharge station relative to the axis of the outlet conduit. Thus, material is propelled through the outlet conduit at an angle relative to the discharge station, changes direction toward the discharge station, and flows through the tube to said discharge station.
