FIELD: agricultural engineering, in particular, shank which may be used in drills for sowing of tilled, groats, and cucurbitaceous crops on soil with stubble remains.
SUBSTANCE: shank has tine with wedge-shaped front, and flat A-hoe disposed in lower part of wedge-shaped front. Seed guide, fertilizer guide and coverer are positioned rearward of tine. Disk knife with beads is placed in tine aperture. Disk knife is made in the form of flat ring having cutting edge provided at outer diameter and is equipped with furrow cutter made in the form of opposite hollow truncated cones positioned with their larger bases and joined with their beads formed as hollow cylinders. Beads are mounted on axis of rotation. Seed guide is positioned in plane of furrow cutter. Lower end of furrow cutter has skew cut. Cavity between seed guide and fertilizer guide is closed with shield.
EFFECT: increased yield of crops and reduced production costs.
