<p>A plough with a device for adjusting the centre of gyration of the plough and the centre of guiding of the tractor comprises a four-bar linkage (35) with two longitudinal control rods (2, 3) and a setting element (16) for adjusting, and a setting member (61) supported on the plough frame for setting the working width per element with an adjusting member (64) mounted on the frame. The adjusting member (64) is connected to the four-bar linkage (35) by a transmission lever (67) the adjustment of which is effected by setting the working width, and rectifies and compensates the adjustment of the four-bar linkage (35) and of the setting member (61) so that the working width and centre of guiding remain constant.</p> |
