ABSTRACT:
An apparatus for spreading loose material, such as gravel, on a surface. The apparatus comprises an elongate material spreader for positioning generally parallel to the surface a distance above the surface. A frame extends forwardly and above the spreader to a pivotal connector for connecting the apparatus to a hopper trailer between the trailer and the surface. A first material retainer extends forwardly from the front of the spreader near one end of the spreader. A second material retainer extends forwardly from the front of the spreader. The first retainer is positionable a distance from the second retainer so that, when the material is distributed from the trailer a distance from the front of the spreader in a forward direction, the material is spread between the first and second retainers and between the bottom edge of the spreader and the surface, as the trailer moves in the forward direction along the surface.
