FIELD: agricultural engineering, in particular, tillage and sowing technique.
SUBSTANCE: combined tillage and sowing shank has seed guide formed as hollow column, stabilizer, seed distributor, chamber, soil guiding plates, restricting device, soil compaction device, plate, A-hoe with tine, and seeding chamber. Two-sided trifacial wedges are fixed on A-hoe above soil guiding plates are equipped with left-hand and right-hand moldboards positioned behind each of two-sided trifacial wedges. Moldboards are secured to wedge rear faces so as to move in longitudinal-vertical plane. Left-hand wedge is equipped with right-hand moldboard, and right-hand wedge is equipped with left-hand moldboard.
EFFECT: improved sowing quality due to more uniform distribution of small-sized soil fraction above seeds.
