ABSTRACT:
A compression system for a dual material delivery assembly is described. The assembly includes a furrowing element for producing a furrow in the ground as it is towed across the ground. A fertilizer tube and a seed tube are provided for depositing fertilizer and seed at respective location in the ground. A packer wheel follows the tubes for packing earth on top of the seed. A biasing element provides a force on the furrowing element and the packer wheel. A control linkage mounts between the packer wheel and the furrowing element for controlling a distribution of the force between the furrowing element and the packer wheel.
