Abstract:
Towing device for an agricultural apparatus (2), comprising at least one wheel (6) which is arranged in a front area of the agricultural apparatus (2) and can rotate about an essentially horizontal wheel axle (8); a link arm (10) which is connected to the wheel axle (8) and is coupled in an articulated manner to a frame (4) arranged on the agricultural apparatus (2) about an essentially vertical first axis (12); and a draw bar (14) which can be coupled to a towing vehicle, characterized in that a control member (22) is arranged to control the pivoting of the link arm (10) about the first axis (12) as the towing vehicle turns, so that the agricultural apparatus (2) turns at least less than the towing vehicle; in that a coupling element (16) is coupled in an articulated manner on the link arm (10) about a second essentially vertical axis (18); in that the control member (22) is coupled in an articulated manner on the coupling element (16) about a third essentially vertical axis (24), and in that the control member (22) is coupled in an articulated manner on the frame (4) of the agricultural apparatus (2) about a fourth essentially vertical axis (26), so that the control member (22) controls the pivoting of the link arm (10) about the first axis (12) as the towing vehicle turns; and in that the draw bar (14) is connected to the coupling element (16).
