FIELD: agricultural engineering, in particular, preparing of soil for one pass to provide sowing by means of any self-propelled power supplied vehicle. ^ SUBSTANCE: cultivator has frame with carrier wheels. Metal triangular flat hoes and pulling mechanism for chain-type rotating module are mounted on frame. Mellowing teeth are fixed to each link of said chain, which is mounted in rear part of frame. Frame is composed of arcuate and rectilinear beams whose ends are connected to one another. Vertical tines of working tools are attached to beams. Working tools are formed as curved plates with faceplates on their cutting edges or in the form of double-convex plates. Teeth of chain sweep have flattened shape and are mounted at an angle to chain longitudinal axis. Number of teeth on one link is unlimited. ^ EFFECT: reduced weight, simplified construction, reduced draft against movement of working tools and provision for uniform leveling of soil. ^ 3 cl, 14 dwg |
