ABSTRACT:
A spreading implement has laterally extending conveyors of different lengths that form a boom to each side of a hopper. At the outer ends of the conveyors, rotatable spreading discs are mounted spaced apart from one another and each conveyor is an endless belt in a channel shaped guide. A slideable flow control is positioned beneath a port in the bottom at each side of the hopper to regulate the amount of material fed to the conveyors. Driving means, including a power take-off connection and a belt and pulley transmission move the conveyors and rotate the discs. At the end of each conveyor, a downwardly extending guide allows material to flow to a lower disc. Each boom is pivoted to the implement frame with a latch and pivot connection to be displaceable about a vertical axis to a rearwardly extending transport position. Also, each boom is comprised of spaced apart beams that are comprised by two portions that are interconnected with a further pivot and a latch connection. Upon striking an obstacle that overloads the latch, the outer boom portion can pivot rearwardly or the entire boom can so pivot. The conveyor belts and drive connections are slackened when the boom or its portions are pivoted with respect to one another. The discs can be mounted to rotate about axes located to the rear of the center lines of their respective conveyors. An eccentric drive connection moves an agitator above each port to ensure a steady flow of material to the discs.
