ABSTRACT:
An unloading system for a container, such a forage box, includes a floor and a pair of parallel sidewalls. An auger is located in the container and a hydraulic motor on the auger rotates the auger to convey material in the container toward one end thereof. The auger is mounted on movable carriages and a second hydraulic motor drives the carriages to advance the auger transversely across the floor of the container between the sidewalls while the auger is rotating. A second cross auger is positioned adjacent the discharge end of the aforementioned auger and extends transversely of the container to receive the material conveyed by the first auger and discharge it from the container, and the second auger is also driven by a hydraulic motor. The hydraulic motor which transversely advances the first auger includes a relief valve which controls the hydraulic fluid pressure of that motor to vary the speed of the transverse movement across the floor of the container.
