  • Patent number: 4244306
    Abstract: A planter for seed crops, such as grains. A wheeled framework supports the apparatus for movement about a field. At the front of the framework is a row of transversely spaced chisels which produce tilled areas parallel to the path of movement of the framework and separated from one another by strips of untilled soil. Each chisel carries a roller that breaks up any resulting clods of soil. Liquid fertilizer is directed to the tilled areas by delivery conduits extending along the rear of each chisel to their respective lower ends. The rollers provide a cover of soil to the liquid fertilizer. A drill apparatus is mounted to the framework behind the chisels, with individual openers in longitudinal alignment with the respective chisels for planting seeds in the tilled soil at an elevation above the elevation at which fertilizer has been supplied and without the strips of untilled soil.
