FIELD: agricultural production, in particular, equipment for drilling of grass seeds in sod. ^ SUBSTANCE: drill has frame carrying rotavator section, seed box with seeding units, and covering rolls. Rotavator section has tillage tools made in the form of two disks with L-shaped knives and is covered with housing. Two-sided moldboard located within housing is made in the form of two joined surfaces, namely, right-handed and left-handed surfaces extending in longitudinal-vertical plane. Width of moldboard is equal to at least distance between wing edges of inner L-shaped knives turned so that these knives face each other. Rotavator cutter drive is extending centrally of housing. Seed guides are located in rear part of housing. Pressure applied to soil by rotavator section and covering rolls is adjusted by means of springs. ^ EFFECT: increased efficiency owing to complete returning of soil into tilled strip, with herbage in untilled part of land being kept, to thereby improve quality of sowing grass seed into sod. ^ 2 cl, 5 dwg |
