FIELD: agricultural engineering, in particular, equipment for soil tillage and thinning of tilled crops. ^ SUBSTANCE: working tool has hoe connected to tine and carrier fixed on frame by means of upright pivot joint. Probe mounted on carrier by means of pivot joint and spring is adapted for withdrawal of hoe from row. Hoe is made symmetrical. Probe is mounted on carrier through rocker arm, two pivot hinges and two springs for pressing probe to soil surface and acting upon carrier during moving around plant. In addition, probe is provided with stop for controlling approach thereof to plant. Also, probe is mounted so that its position relative to hoe blade may be adjusted. In order to alter force of pressure applied to plants and soil, extension of springs may be regulated. ^ EFFECT: increased efficiency and reduced damage to cultured plants during thinning procedure. ^ 3 cl, 2 dwg |
