FIELD: agriculture. ^ SUBSTANCE: invention relates to agricultural engineering and can be used for making furrows and sowing crop seeds. The ploughshare comprises tip, compactor and guide for seeds. The compactor is worked out as a roller with rhombic cross section profile. Tapered teeth are set circumferentially on the outer surface of the compactor. The teeth are made as quadrangular pyramids. One face of each tooth is directed radially to the compactor centre. Tooth side faces are of right-angled triangle form. Acute angle at the tapered tooth base accounts for 27 at least. ^ EFFECT: increased uniformity of seeds distribution in a row. ^ 2 dwg
