Abstract: A reversible plough with a frame for a 3-point hitch attachment comprises a frame with lower first and second and an upper third attachment point for attachment to a 3-point hitch. A vertical pivot axle supports a plough tool carrier for pivotable movement. The upper third attachment point is located on a vertical pivot plate in a first upper pivot point. A second lower pivot point of said plate is connected to a transversel pivot axis on the frame and a third upper pivot point of said plate is connected to a control link. When the upper link of the 3-point hitch moves backwards, then the plate pivots and moves the control link backwards as well. Said control link extends towards the rear end portion of the frame and is connected to a link arrangement pivotally supported by the vertical pivot axle and connected to the plough tool carrier.
