Abstract
A grain cart has a wheel supported container with an inclined auger unloading conveyor having an inclined lower section positioned to receive grain from the container and an upper section supported for folding movement between a stored position adjacent the container and an inclined discharge position projecting upwardly, forwardly and laterally outwardly from the left side wall of the container. The upper section of the auger conveyor has a tubular housing with an askewed discharge spout supporting a pivotable flow control spout for tilting movement on a horizontal axis extending parallel to the left side wall of the container for discharge of grain laterally across an open top rectangular semi-trailer within a vertical plane perpendicular to the left side wall of the cart. The flow control spout is tilted by a remotely controlled actuator for filling and topping off the semi-trailer including all four corner portions of the trailer.
