FIELD: agriculture.SUBSTANCE: basin harrow comprises a handle, a cone-shaped tip, a limiter of cone-shaped tip depth in the form of a circle, a support platform. The basin harrow additionally comprises a telescopic cross beam, comprising the main and sliding beams of square or rectangular section with a fixator of sliding beam position relative to the main one. On the main beam above the one perpendicular to it a handle is fixed, and the support platform is placed nearby. At the bottom of the main beam coaxially with the support platform there is a cone-shaped tip. On the free end of the sliding beam at the bottom there is a knife fixed with a horizontal plane of "?"-shaped section to cut a mulching film with a limiter of knife submersion into mulched soil. The limiter of knife submersion has a shape of a square or rectangular plate bent outside from the knife upwards along the circumference arc in the longitudinal-vertical plane. Cutting edges of the knife are arranged relative to the soil surface at the angle of at least 45°.EFFECT: proposed invention expands functional capabilities of a device.2 cl, 4 dwg |
