Bracket formed as triangular prism is located in each spacing between flat triangles of A-hoe. Bracket is welded to lower part of tine and is provided with milled slot whose bottom is extending in parallel with sharpening line. Slot is equipped with set of threaded openings. Flat chisel with lower sharpening and aperture at the end opposite to cutting edge is inserted into slot and fixed in cantilevered relationship by means of screw. Depth of slot is limited by connecting member welded to bracket prism apex at height equal to height of chisel. Apparatus is further provided with set of replaceable triangles forming hoes and defining width of 125, 200 and 500 mm. Hoes are equipped with trapezoidal agitators.

EFFECT: reduced consumption of power for tillage procedure, enhanced reliability in operation and wider operational capabilities.
