摘要:
A seed drill for applying seed and/or fertilizer has a frame, reservoir, and sowing shares. The sowing shares are attached to the frame in such a way that they can move in an upright plane by means of superimposed and at least approximately parallel struts on parallelogram mounts. To essentially improve the share mounts, allowing them to be employed on direct-sowing seed drills and especially on soils thickly set with entrenched stones or other obstacles and preventing damage to the shares or share mounts when the shares are laterally overstressed, at least one strut on a parallelogram mount is elastic.
