Drainage plough consists of a main support for working elements (1) whereto are from the bottom connected working elements (5) and (6) to form elongated profiled closed channels. The main support of working elements (1) is tied to the main longitudinal beam (3) by means of a system (2) for fixation and adjustment.Drainage plough is connected to the system by means of a tractor levers in three points: by means of shoes (10) onto the bottom tractor links. Depth of production of longitudinal profiled channel is adjustable, and the wheels (7), are used to abut thereon. When the drainage plough is not connected onto the tractor levers, its front part rests onto the ground by means of supporting rests (9).
