ABSTRACT:
A no-till drill mounts a seed distribution assembly on the upper portion of the back side of a chisel blade that cuts a furrow in the soil being planted. The seed distribution assembly includes a horizontal seed distribution plate having an upturned lip at its rear edge and side walls which extend upwardly from each of its sides. The side walls are joined to the blade at one of their ends and their other ends are separated from the upturned lip of the seed distribution plate. Thus, seed which is deposited onto the seed distribution plate from a seed supply tube falls off of the rear portion of the plate between the ends of the side walls and the upturned lip. The seed distribution assembly is wider than the blade and is positioned to extend partially into the furrow made by the blade and widen the upper portion of the furrow. Thus, the seed which falls off the sides of the seed distribution plate lands on ledges which are formed between the upper and lower portions of the furrow and remains separated from the fertilizer which is deposited at the bottom of the lower portion of the furrow by a fertilizer supply tube. A packer wheel, which follows each blade and drill, is pivotal about a vertical axis so that it remains parallel with the direction the blade and drill are traveling even when the device is being pulled across transversely sloping terrain which causes it to tail.
