Abstract
In the plough according to the invention, a bottom-blade swivel segment and a blade flap arranged at the other end of the plough are positively coupled via a lever mechanism which consists of a rocker which is pivotably mounted on the plough body and to which the bottom-blade swivel segment and the blade flap are in each case connected via a steering rod interposed in an articulated manner. The connecting joint of the steering rod connected to the bottom-blade swivel segment at the rocker is located at a greater distance from the rocker joint than the connecting joint of the steering rod connected to the blade flap, as a result of which the different swivelling displacements of the bottom-blade swivel segment and of the blade flap are taken into account.
