A device for regulating the speed of an auger utilized to deliver grain or similar particulate material from one location to another. A motor driven, constant speed shaft carries a concentric disk which rotates with the shaft and which is tiltable relative to the axis of the shaft. A pair of reciprocal drive couplers is connected to the shaft of the auger and is utilized for imparting one-directional rotative movement to the auger. A pair of rocker arms is operatively connected between the drive couplers and the disk carried by the drive shaft. Each rocker arm has one end connected to a drive coupler and its opposite end resting upon one side face of the disk. Rotation of the disk when in a tilted position causes oscillatory movement of the rocker arms and the resulting actuation of the drive couplers, which in turn cause rotative movement of the auger. The disk carried by the drive shaft is designed so as to be adjustably tiltable relative to the axis of the drive shaft. By varying the tilt of the disk, the extent of oscillatory movement or swing of the rocker arms may be varied and the speed of the auger correspondingly changed.
