Abstract: Disclosed is a pneumatic spreader for distributing materials stored in bulk supply in a hopper. The hopper includes an opening for discharging the materials into the upper portion of a chamber which includes a metering roller. A lower portion of the chamber is connected to a forced air supply and includes a distribution channel defining a plurality of flow paths. Nozzles receiving metered material are placed in the distribution panel, with one nozzle corresponding to a particular flow path. Material exits the nozzle immediately adjacent the flow path defined by the distribution panel. Forced air fluidizes the material as it enters the distribution panel in the desired direction of the flow path. Flexible tubing sections defining major portions of the flow panel are connected to the distribution panel. Ends of the flexible tubing sections remote from the distribution panel discharge the material. The free ends of the tubing sections are arranged along a boom to form a preselected pattern.

Abstract: The portable, self-unloading fertilizer tender comprises a frame suitable for mounting on a truck or trailer for road and ground travel, a hopper mounted on the frame with a discharge opening at its bottom, a longitudinally extending auger tube in communication with the hopper, an auger mounted in the tube and support means for the tube. The discharge opening of the hopper is spaced longitudinally from at least one end of the frame, and the hopper end wall on that end of the frame slopes downwardly and inwardly toward the discharge opening. The entire auger tube is pivoted at its intake end about a transverse, horizontal axis adjacent the discharge opening of the hopper. The intake end has an opening in registration with the hopper discharge opening. The discharge end of the auger tube can be selectively adjusted in vertical elevation between a lowered, traveling position and at least one elevated, discharge position by support and retention means.
