FIELD: agricultural engineering, in particular, drill shanks for sowing of cucurbitaceous crop seeds on unirrigated land and embedding seeds to low depth into wet soil and retaining seeds in furrow and mulching from the top with dry thin layer.
SUBSTANCE: shank has ridger, shank slides, compactor, and covering device for returning of dry soil layer, said parts of shank being arranged in succession one behind another. Compactor is made in the form of two spherical disks arranged at an angle to vertical plane. Covering devices for returning of dry layer and mulching are made in the form of two brushes.
EFFECT: improved quality of sowing due to uniform seed distribution and providing complete contacting thereof with soil.
