FIELD: agricultural engineering, in particular, technique for tillage of soil on the fields with prevailing precipitation moisture-impermeable portions. ^ SUBSTANCE: tillage apparatus has rectangular welded frame with hanger system, tillage depth adjustment system, working tool attachment system, and working tools made in the form of tines with beveled lower part. Bracket with opening is fixed to mid portion of each tine. A-shaped half-hoes are pivotally secured at sides within openings by means of fastening pins fitted with threaded ends. Half-hoes may be folded and unfolded and have retainers for fixing said half-hoes in predetermined position. Tines have rectangular section, with lower front part formed as knee. Each tine is provided at its front side with triangular chisel having pins for attachment to tines and threaded openings. Additional brackets with openings are mounted in rear part of tines. Fastening spindles are screwed into chisel threaded openings through apertures provided in brackets located in middle and rear parts of tines, said spindles being adapted for fixing of A-shaped half-hoes through tubular brackets equipped with rotational angle restricting devices. Trapezium-shaped stirrers are mounted on half-hoes. ^ EFFECT: reduced consumption of power and enhanced reliability in operation. ^ 5 dwg |
