FIELD: agricultural engineering.

SUBSTANCE: invention can be used in agriculture for sowing grain and other seeds on different soils. Proposed unit has frame with support pneumatic wheels, cone-like hoppers for seeds and fertilizers with sowing units, rear and front drive drums for packing of soil and control of plowing depth, respectively, and colters, all mounted on frame. Colters are made in form of rhomboid plate. Post is installed from one side on said plate with tilting. Cutting member with sharp point to cut soil layer is rigidly secured in front part of post. Two additional cutting members are installed at both sides of first cutting member. Sowing units are made in form of stirring plates and detachable plates with conical sockets. Stirring plates are installed in hopper slots, their upper part being arranged inside hoppers, and lower part, outside. Last sockets are arranged at definite distance from each other, their height being equal to height of stirring plates. The latter are set into reciprocating rotation by mechanisms. Lower part is curved at angle of 15-20^o, and upper part has height of 90-95 mm. Plates with sockets are installed from side of slot between stirring plates and wall of hopper.

EFFECT: simple design, reliability in operation, reduced consumption of power.
