Abstract: A low profile trailer adapted for use with bulk material containers having either a central discharge port, or a side discharge port. The trailer includes a trailer bed having a pair of container decks each adapted to receive and support a bulk container. Each of the container decks has both a central discharge opening and a side discharge opening disposed to register with the central and side discharge ports of various bulk containers. A retainer lip extends up from and around three sides of each container deck so that a rigid bulk container may be loaded on the container deck with a fork lift and be conveniently positioned and secured on the deck. All discharge openings communicate with a hopper located under the trailer bed, and a hydraulically powered auger is used to discharge material, such as seed, from the hopper to the seed boxes of a planter.
