A grain cart has a wheel supported frame on which is mounted an open top container having inclined bottom walls and including a discharge auger conveyor having a lower section extending from a sump for the container adjacent a front left inclined corner portion of the container. The auger conveyor has an extended upper section supported by a hinge assembly having a pivot axis offset and askewed at an acute angle from the auger axis. The hinge assembly provides for pivoting the upper conveyor section between an inclined grain discharge position projecting upwardly, laterally outwardly and forwardly from the container and a stored position inclined downwardly at a substantial angle from the hinge assembly in front of the container. In the stored position, the grain discharge outlet is located lower than the top surfaces of the wheels.
