FIELD: agriculture.
SUBSTANCE: rotary tiller comprises two conical rotary harrows with ripping teeth connected to hubs with the possibility of rotation around horizontal axis. Rotary harrows consist of annular rims of large, medium and small diametres, which are connected to each other by means of scraper-planks along their generating surfaces. At the same time rotary harrows are installed on composite crank axis made of three parts, central crank axis and two side axles. Besides connection of axles to crank axis is carried out by means of coupling, with further fixation by counter nuts, and on axles, in inner cavity of harrows, there are scraper-wipers are mounted.
EFFECT: invention provides for higher efficiency of weeds destroying and soil tillage, and also prevention of harrow clogging with soil into earth lump.
