Abstract: A trailer for dispensing different types of bulk material such as seed into planting equipment is disclosed, the trailer including a pair of substantially planar platforms with an elongated conveying bin disposed below and between the platforms. Seed from one or more of the bulk bags falls into the bin and is conveyed by way of an auger forward to a hopper located at the ends of the platforms. From the hopper, the seed is dispensed into planting equipment by way of a pivotally mounted elevated auger which swings in about a 180.degree. arc so as to dispense seed on both sides of the trailer. The elevated auger and corresponding tube are mounted to the trailer by way of a hanging pivot member which enables the auger to pivot between a dispensing position in which the intake end of the auger is located in the hopper and a storage position where the auger tube extends rearwardly above the platforms.
