The invention relates to a 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. A control member (22) is arranged between the draw bar (14) and the frame (4) in order 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.
