FIELD: agricultural engineering. SUBSTANCE: working tool has disk 1 made curved in two parts. Bending lines are extending parallel one with another and are arranged at distance from center 0 of disk 1 not exceeding distance from center 0 to inner ends of blades 2. Bent portions 5 and 6 of disk 1 are extending in parallel with and deflected from surface of disk central part 7 for an angle of 5-20 deg. Such construction allows mineral fertilizers to be uniformly spread over vast area of field surface. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 dwg
