- a. a frame supported by a plurality of wheels;
b. a storage bin connected to said frame, said storage bin including a first and second pair of opposing sidewalls;
said first pair of opposing sidewalls converging downwardly and inwardly to a trough and a sump extending across a bottom of said storage bin;
said trough extending across a first portion of said bottom of said storage bin and opening into said sump at a discharge end thereof;
said sump extending across a second portion of said bottom of said storage bin and positioned adjacent said discharge end of said trough;
a portion of said sump extending lower than said trough;
said sump opening directly to said bin;
one of said sidewalls of said second pair of opposing sidewalls sloping downwardly and inwardly to an end of said sump opposite said discharge end of said trough;
c. a drag auger rotatably secured in said trough and having a discharge end aligned with said trough discharge end; and
d. an unloading chute secured to said storage bin and having an unloading auger rotatably secured therein;

Abstract
A cart for storing and transporting granular material comprises a storage bin having sidewalls which converge inwardly and downwardly to a trough and a sump. The trough extends across a portion of the bottom of the storage bin and opens into the sump which extends at least partially below the trough. A drag auger is rotatably secured in the trough. An unloading auger assembly is secured to the storage bin and extends from the sump, upward along the front left corner of the bin and therebeyond. A lower portion of an auger of the auger assembly extends into the sump. Grain stored in the bin flows by gravity into the sump where it is advanced out of the bin by the unloading auger assembly. The drag auger may be independently engaged to advance grain to the sump which would not otherwise advance to the sump by gravity feed alone.
