The utility model relates to agricultural tillage machines and can be used in the manufacture of harrows. The technical problem solved by the presented utility model is to expand the operational and technological capabilities, increase the maintainability of working sections of the harrow, as well as reduce the time for maintenance of the harrow. rotational includes a battery of pairs of disks, on horizontal axes with removable wedge-shaped teeth with an oblique cut, with an oval on top spine in the direction opposite to the direction of travel, the wheels are located in front of one another, each under its own furrow. Disks are fixed at opposite ends of a shoulder oriented in direction of movement from different sides, the shoulder is fixed on a curved rod mounted on the trailing frame with the opposite end through a hinge and a spring element. Disks are made of two parts with lodges expanding towards the center of the disk, responding in shape the bases of the wedge-shaped teeth and staggered relative to each other for installation of wedge-shaped teeth in them, which allows you to lay and fasten the wedge-shaped teeth between the disks with reliable fixation against falling out while working in the field. Moreover, the discs are mounted on the shoulder at different distances from the hinge joint, and the disc mounted on the small shoulder is located in the forward direction, which allows for better soil cultivation. The arrangement of the discs on the shoulder pivotally prevents possible damage to the hoe harrow when driving on an uneven surface, which ensures high performance of the hoe harrow. The body of the sphenoid tooth is made of a curved shape with a displacement of the working part relative to itelno base to the right or left or without displacement that provides for different embodiments of teeth installation formation of different variants teeth fields, extend the operational and technological capabilities harrow.
