FIELD: agricultural engineering. SUBSTANCE: shank has tine, seed guide, A-hoe, seed distributing and embedding device. Tine is spaced from rear cut of A-hoe by distance equal to double diameter of tine. Seed guide is installed between tine and A-hoe at an angle to hoe bottom exceeding friction angle of seeds against seed guide. Such construction allows seeds and fertilizer to be uniformly distributed over the entire area of field under cultivation. EFFECT: improved embedding of seeds at uniform depth, increased emergence rate and, accordingly, crop yield. 2 dwg |
