The working body for the rotary harrow with interchangeable tooth assembly is made of sheet metal by plasma cutting of grade 45 steel. When cutting, high temperatures occur due to which the edges of the wheel are quenched. All teeth are fastened with bolted joints, which facilitates tooth replacement in the field. It has 4 holes for mounting the hub. A tooth thickness of 10 mm provides an excellent result in work and high wear resistance. By pressing, 2 SKF bearings, size 204, are installed.
