Abstract
A convertible livestock/grain hauling trailer has front, center and rear compartments, with a second livestock floor in the center compartment. Means are provided for pivoting the floor boards of the second floor downward towards front and rear to define a pair of grain hoppers, and adjustable grain outlet doors are provided in the floor board at the base of the hoppers. Support rail hangers are provided along the side walls of the trailer corresponding to both the horizontal and slope positions of the second story floor boards, and support rails for the edges of the floor boards are movable from either set of hangers to support the floor board in its corresponding position. Front and rear bull gates are optionally pivotable towards the front and rear respectively to further define the grain hoppers, and support rails are provided to hold them in position. Tarps are provided on rollers in the interior of the trailer to cover the livestock ventilation slots when the trailer is being used as a grain hauling trailer.
