  • Patent number: 4294180
    Abstract: Forwardly disposed furrow openers and rearwardly disposed furrow openers are conventionally offset to one side of the path traversed by the forwardly disposed furrow openers. To prevent partial backfilling of the furrows formed by the front openers when the grain drill on which the openers are mounted is pulled at relatively high speeds, a device including a pair of downwardly converging wheels is provided, the wheels being rotatably mounted on the angled end portions of an axle or shaft. The straight central portion of the shaft is firmly clamped in a sleeve at the rear end of an arm which has its forward end clamped to the rear end of a strut pivotally attached to the grain drill. The central straight portion of the shaft can be rotated so as to obtain the best operation of the wheels. In this way, soil that would be plowed into the furrows formed by the forwardly disposed furrow opener is resisted by the circular wheels.

  • Patent number: 4276836
    Abstract: The grain drill includes a furrow opener, a forwardly disposed seed spout, a rearwardly disposed fertilizer spout, and a deflector plate positioned beneath the fertilizer spout so that a desired amount of the fertilizer discharged from the lower end of the fertilizer spout is deflected laterally. The deflector plate is adjustable forwardly and rearwardly with respect to the seed spout so that the amount of fertilizer flowing over the forward edge of the deflector plate can be controlled by the position of the forward edge of the deflector plate with respect to the seed spout.
