TOWED DEVICE WITH CONTROL SYSTEM, HAVING BOTH WHEEL ASSEMBLIES, AND COLTERS Russian patent published in 2017 - IPC A01B63/16 A01B63/32 A01C7/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to tillage and sowing tools. Tool is made with possibility of towing by vehicle, has frame with plurality of tools interacting with soil. Support wheels assemblies are arranged on frame, which can displace relative to frame for its lifting and lowering between working and idle positions, in which tools interact with soil in working position, and in idle position tools do not interact with soil. Each wheel assembly is arranged with possibility to turn about wheel rotation corresponding axis. Colters are also installed on frame and interact with soil only in frame working position. Each colter is installed on frame with possibility to turn about colter rotation corresponding axis. Control mechanism is made with possibility of each of wheel assemblies and colters rotation around their respective rotation axes for tool control.

EFFECT: such design solution is aimed at increasing of tool controlling efficiency during operation in field.
