Abstract

Down-force control is provided by a top-link, which presses down the rear end of a tool-bar carrying multiple rows of seeder tools. The height of the tool bar is set front and rear during operation. The top-link includes a hydraulic ram. The ram is supplied with pressure from a pressure-reducing-relieving valve, whereby the downward-force on the rear of the tool-bar remains constant during operation. The tool bar has side wings which are pressed down by a pressure that is regulated by the same valve.
The system allows the seeder to maintain constant implantation depth, even over uneven ground.
