ABSTRACT:
A device for spreading aggregate material from a discharge conveyor onto a work surface includes a tremie attached relative to the discharge conveyor and a flexible hose connected to the tremie. A crank connected between the tremie and the discharge conveyor permits adjustment of a frequency and an amplitude of the tremie to provide a desired windrow of material on the surface. A distal end of the discharge conveyor is preferably moveable relative to a supply of material to further optimize the desired windrow of material.
