FIELD: agriculture; machine building.

SUBSTANCE: inventions relate to agricultural tillage machines. Rotary harrow-hoe contains a battery of working sections mounted on the frame, each working section consists of a pair of working bodies in the form of toothed disks mounted on curved rods, and the frame is equipped with elements of connection with energy means. Novelty consists in the fact that each working section is fixed on the frame by means of a clamp and base, with working bodies mounted on it by means of copying units consisting of hinges, on the sleeves of which copying elements with rotation stops are installed under the lower plane of the frame, on the copying elements curved rods with toothed disks are fixed, at the same time, the working bodies are equipped with stabilizing units consisting of springs fixed by one ends on curved rods, and the other ends on the base. Variants of the invention – a toothed disk of the working body has common essential features of the restrictive parts of independent claims: teeth and hub. Variants of the toothed disk of the working body and their novelty are due to the fastening elements of the bases of the teeth.
