FIELD: agricultural engineering, in particular, small-sized tillage equipment for interrow tillage of farm crops or soil in gardens, home ground and in greenhouses. ^ SUBSTANCE: hand-held tillage tool has cart with frame, and engine, working tool and control levers, which are mounted on cart frame. Vertical pins-shafts are mounted at cart frame front and rear parts along axis of symmetry. Vertical frames are mounted on shafts for rotation in horizontal plane. Working tools have horizontal undercutting part and side knives adapted for undercutting soil in vertical plane. Working tools are fixed on frames connected with control levers and with one another by means of rigid or flexible tie-rods. Tie-rods for connection with frames are made in accordance with different versions. Knives are equipped with cleaning disks and device for imparting vibratory motions to knives for reducing of working tool draft. Kinematic circuit is adapted for transmitting of rotational motion from working tool engine to cleaning disks and of vibratory motion to knives. ^ EFFECT: reduced labor intensity for operator, increased maneuverability of tillage tool and reduced load applied to engine due to reduced angle of rotation of working tools while providing predetermined radius of rotation of working tool. ^ 17 cl, 13 dwg |
