A seed dispenser for agricultural planters has a casing forming a seed-receiving chamber and within the chamber, turning on a transverse axis, is a seed plate or wheel having seed-receiving cells on both radial faces. The wheel is in effect a rotating partition which divides the chamber into right and left compartments. One of the compartments receives seed, as from a hopper, and the wheel has one or more through openings so that the seed flows from the one compartment to the other. Both compartments lead to a seed outlet through which seeds are discharged to the ground, furrow, etc. The arrangement doubles the output of seed from the dispenser and thus enables more efficient planting according to modern agricultural methods. |
