Dual material agricultural delivery system for seeder

摘要

A compression system for a dual material delivery assembly for mounting on a frame alongside a plurality of similar assemblies is described. The assembly includes a furrowing knife for producing a furrow in the ground as it is towed across the ground. A fertilizer tube is mounted behind the furrowing knife. A seed dispensing tube provided is for depositing seed in the furrow behind the fertilizer knife offset to one side and above the fertilizer. A packer wheel is attached to the seed tube assembly. The fertilizer knife and the seed tube assembly are separately mounted on a bracket attached to the implement frame for pivotal movement about a common pivot Two separate cylinders are provided to apply a separate force on the furrowing element and the packer wheel. The cylinders of each of the assemblies are commonly connected for common adjustment on the frame or on the go on a tractor towing the frame.
