ABSTRACT:
A spreader implement attachable to the rear of a tractor has a container with two side by side funnel shaped sections. A port in the bottom of each section allows material to pass to conveyor belts that extend laterally to each hopper side. A flow control member is slideably positioned below each port with one or more openings that correspond to each belt, which openings can be more or less exposed by an adjusting device. The conveyor belts are supported on a foldable boom at each lateral side of the container and each belt leads to a respective rotating spreading disc and the belts extend for different distances so that material is spread over a very broad path. Each spreading boom includes beams and supporting guides for the upper and lower runs of the belts. Guide members are positioned below the flow members to direct material to the upper conveyor runs. Each boom is interconnected to the implement frame via its supporting beams and is pivotable about a vertical axis when a spring-loaded latch is tripped and also about a horizontal axis. Each boom has inner and outer portions of about equal lengths which are pivoted to one another by a substantially vertical shaft. A supplemental chain support interconnects the top of the container with the boom adjacent the shaft so that each boom can be folded about the shaft and pivoted to a rear trailing position relative to the frame for transport with the chain still providing support. An outer portion of each boom has a sliding ground support and marker.
