The invention described herein is a vehicle-based feed distribution system comprising: a hopper assembly where a metal ball is located in a hopper outlet located at a bottom portion of a hopper, where an auger inside a horizontal dispensing tube is driven by an auger drive means that directs a feed mix from a hopper longitudinally down the horizontal dispensing tube extending out from the hopper outlet, and where a feed outlet at a distal end of the horizontal dispensing tube distributes the feed mix; where the hopper assembly is coupled to a tow vehicle, and where the tow vehicle controls the auger drive means to meter distribution of the feed mix.
