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.
