Tine of deep plow and tine of previous plow body are arranged in single longitudinal-vertical plane. Inclined part of deep plow is formed at an acute angle to vertical plane. Horizontal share of deep plow with chisel fixed to its point is oriented forward with its angle. Chisel fixed at deep plow point is spaced from share shoe of plow body by distance of at least: L=h_max˙sin ω, where h_max is maximal tillage depth of deep plow, cm: ω is angle of natural soil shear, degree.

EFFECT: increased efficiency by reduced draft.
