Abstract: A swing auger towable by a tractor features a main auger, and a feed auger pivotally coupled to the main auger and reaching transversely outward therefrom. One or more additional conveyors each are positioned alongside the tractor with the discharge of the conveyor(s) feeding into the feed auger, and with the conveyor hopper positioned longitudinally forward of the tractor under the bottom discharge of the trailer or other source receptacle. A stabilizing device for the main auger doubles as a lift arm for elevating the conveyor in a transport position, and may be installed with a tandem axle that compensates for angular frame variation in the working position of the main auger. Alternatively, a novel auger frame is pivotally coupled to the inlet end of the main auger, remains at a consistent angle regardless of the main auger's position, and is equipped with a hitch connector and rear stabilizer arms.
