DISC HARROW WITH OPTIMAL ARRANGEMENT OF ELEMENTS Russian patent published in 2022 - IPC A01B7/00 A01B21/08 A01B73/04 

FIELD: agriculture.

SUBSTANCE: tillage tool (10) with a central longitudinal axis contains working bodies (28), in particular disc tools arranged in at least three rows (30.1…30.3) with at least two rows (30.1…30.3) following each other in working direction (A), perpendicular to working direction (A), and a running gear with at least one or two main wheels (20.1, 20.2) located perpendicular to working direction (A) and displaced relatively to central longitudinal axis (22) within wheel distance (dr). The running gear is located relatively to working bodies (28) in such a way that there is at least one specified row (30.1…30.3) of working bodies in front of the running gear relatively to working direction (A), as well as on the left and right of it. All working bodies (28), which, in working direction (A), are located in row (30.1), which is the most remote from the running gear, are located within side working body distance (ds) from central longitudinal axis (22), which is less than or equal to side wheel distance (dr). The running gear is within at least one of rows of working bodies (30.1…30.3), perpendicular to working direction (A). Row of tools (30.1…30.3) located along working direction (A) the furthest from the running gear, in front of it does not go out of limits of the running gear along a width across working direction (A).

EFFECT: high maneuverability, careful starting, and uniform tillage, as well as compactness and efficiency of a tool.
