Abstract: A bulk seed cart includes a seed bin with sloping sides converging at a bottom mounted discharge hopper to which a conveyor is removably connected for unloading seed from the cart. The conveyor is supported by a telescoping boom mounted on the side of the cart and the boom, and attached conveyor, can be raised or lowered via an attached hydraulic lifting cylinder. The boom can be pivoted from side to side and the conveyor is attached to the boom via a swivel assembly, which, once the conveyor is detached from the seed cart, allows the conveyor to be swiveled 180 degrees and attached to a nearby source of seed, such as another seed cart, a stationary bin, a truck or railroad car, etc., with the conveyor being directed toward the seed bin in the seed cart. Seed can thus be unloaded from the source and loaded into the seed cart via the conveyor. The lifting cylinder, the telescoping boom and the conveyor motor are all controllable via a single remote control module.
