Claim:
A containment assembly moveable along a direction of travel for containing a granular material, comprising: a frame; a pair of ground engagement wheels rotatably coupled to the frame; a first tank coupled to the frame, comprising: a first tank fore end; a first tank aft end spaced apart from the first tank fore end; a first tank longitudinal axis defined between the first tank fore end and the first tank aft end, the first tank longitudinal axis substantially parallel to the direction of travel; a first tank length defined between the first tank fore end and the first tank aft end; a first tank left side extending between the first tank fore end and the first tank aft end; a first tank right side spaced apart from the first tank left side extending between the first tank fore end and the first tank aft end; a first tank width defined between the first tank left side and the first tank right side; and a first tank bottom surface extending between the first tank fore end, the first tank aft end, the first tank left side, and the first tank right side; said first tank bottom surface gradually slopes and defines a longitudinal pocket; wherein the first tank further comprises an auger proximate the first tank bottom surface for augering the granular material toward the first tank aft end; wherein said pocket receives the auger; wherein the first tank bottom surface is contoured to direct the granular material toward the first tank aft end; and wherein the first tank length is greater than the first tank width; and a second tank coupled to the frame, comprising: a second tank fore end; a second tank aft end spaced apart from the second tank fore end; a second tank longitudinal axis defined between the second tank fore end and the second tank aft end, the second tank longitudinal axis substantially parallel to the direction of travel; a second tank length defined between the second tank fore end and the second tank aft end; a second tank left side extending between the second tank fore end and the second tank aft end; a second tank right side spaced apart from the second tank left side extending between the second tank fore end and the second tank aft end; a second tank width defined between the second tank left side and the second tank right side; and a second tank bottom surface extending between the second tank fore end, the second tank aft end, the second tank left side, and the second tank right side; wherein the second tank bottom surface is contoured to direct the granular material toward the second tank aft end; and wherein the second tank length is greater than the second tank width; wherein one of the first tank left side and the first tank right side are proximate one of the second tank left side and the second tank right side.
