This application discloses a device for urging bulk material to flow from a hopper such as the hopper of a railway car. The device includes a rotating axle that can be rotated by a power wrench, and one or more rotating agitators having auger coils disposed near the bottom outlet of a hopper and which are rotatably connected to the axle. Rotating the axle causes the agitators to rotate, thereby breaking up and urging bulk material to flow downward through the bottom outlet. Also disclosed is a system for emptying a hopper such as the hopper of a railway car, wherein a device with rotatable agitators having auger coils is integrated with a sliding gate assembly situated at the bottom outlet of the hopper. A power wrench can be used both to open and close the gate assembly, and to rotate the agitators in the hopper so as to break up and urge bulk material downward and out of the hopper through the opened gate assembly.
