A mounted rotary plough comprises a transversal mounted bar, which is installed on a tractor, with a vertical post, a rotary frame with an axis, hingingly connected with the mounted bar in such a manner as to allow a relative turn in the vertical plane, left and right plough bodies, fixed from two sides of the frame, supporting wheels and a device of reversing turn of the frame, having an actuating device, which interacts with the frame, and a drive, made as a hydrocylindre, the body of which is hingingly connected with the vertical post of the mounted bar, and a rod is hingingly connected with the actuating device. According to the invention, the actuating device of the device of reversing turn of the frame is made as as a chain-drive with a lowering gear-ratio, a driving chain-wheel of which is hingingly fixed on the axis, horizontally fixed on the vertical post of the mounted bar, in such a manner as to allow turning, a driven chain-wheel is rigidly put on the axis of the rotary frame, and a rod of a hydrocylindre is hingingly connected with the driving chain-wheel with the aid of a pivot, fixed on the disk of the mentioned driving chain-wheel eccentrically. Converting the forward movement of the rod of the hydrocylinder into rotary movement of the frame with the aid of simple rotary gearing improves the exploitation reliability of the plough.
