The frame is made as longitudinal ribs converging from the base to the top. Left and right frame side ribs are rigidly jointed to the bearing rib thus forming a V-shaped girder. One of the frame side ribs is connected to the turning hydraulic cylinder rod. The back end of the frame bearing rib is mounted in a bearing support and can rotate around its vertical and horizontal axles. A hinge set in a provided groove of the bow-shaped guide is mounted at the front end of the frame bearing rib. The left and right plough bodies are fixed at the left and right ribs of the frame respectively. The carrier wheels with an individual adjustment drive are mounted at the frame top. The turning hydraulic cylinder is mounted on the platform. The bearing support is coupled with the turning hydraulic cylinder rod and its vertical axis is matching the longitudinal axis of the vehicle.

EFFECT: invention allows for the improvement of the plough reliability and simplification of the turning unit design.
