PLOW BODY Russian patent published in 2019 - IPC A01B15/00 

FIELD: agriculture.

SUBSTANCE: invention can be used in basic tillage. Plow body comprises a blade made in the form of a stepped surface. Stepped dump surface is made in the form of four horizontal steps located on the dumping surface along radius of curvature. Surfaces of risers of stepped dump surface are located at angle of 45° relative to horizontal planes drawn perpendicular to surfaces of steps through transition lines of stepped surfaces into sub-step. Plow-dump surface consists of five horizontal steps located on the plowing-dump surface on the radius of curvature, the first of which is a plow surface. Length of projections of risers to horizontal planes drawn perpendicular to step surfaces through stepped surfaces transition lines into sub-stepped ones, i.e. protrusion of the surface of the first step relative to the second one, the second one – relative to the third stage, the third one – relative to the fourth stage, and the fourth one – relative to the fifth stage, make 8–10 mm.

EFFECT: high-quality loosening of the arable layer of repacked old-cultivated soils is provided.
