  • Patent number: 4234109
    Abstract: A material-distributing implement which is mountable to the flat bed of a truck for distributing dry material in one configuration and liquid in a second configuration. The disclosed embodiment includes a frame, a hopper, three auger sections mechanically coupled in line with each other and an arrangement of mechanical components and features for converting the implement from the dry material configuration to the liquid configuration and back to the dry configuration. A first auger section driven by the truck's power take-off is supported between the front and rear walls of the hopper. Dry material in the hopper is transferred through an aperture in the rear wall to a second auger section which is also mounted to the bed of the truck. The final auger section receives the dry material from the second section and transfers this material to a remote location, beyond the rear of the truck, for distribution.
