FIELD: agricultural engineering, in particular, sowing of cereal crop seeds with minimal soil tillage operations.

SUBSTANCE: apparatus has hitch frame, drill driven by power shaft of self-propelled power means, hydraulic cylinder, two pontoons provided under frame and adapted for resting of machine upon said pontoons when machine is in operating position, V-shaped shares, and share cleaning mechanism. Mechanisms for preparing of soil for making seed beds are positioned in front of shares and are made in the form of conical disks divided into spiral sectors having two surfaces. First surface of sector is made sharpened and has lower leading angle than second surface. Disk is mounted on vertical shaft pivotally secured on bar connected to hydraulic cylinder. Set of spring-loaded skis positioned after share before second pontoon are equipped with coverers formed as plates located on horizontal pins.

EFFECT: wider operational capabilities of apparatus and reduced consumption of power for preparing of soil for making seed beds.
