A steering gear for controlling an implement (3; 103) suspended in front of a tractor (2), with a yoke structure (9; 109; 209; 309; 409; 509; 609) for coupling to a tractor (2), a steerable part (8; 108; 208; 308; 408; 508; 608), and at least two transmission structures, spaced apart in transverse direction, between the steerable part and the yoke structure. During lateral movement to the left of the steerable part, it is steered rightwards by the transmission structures and vice-versa. The steerable part at one engagement position is displaced forwards and at the other engagement position it is displaced rearwards at least immediately or within a specific lateral movement path less than the forward displacement at said one engagement position or is substantially not displaced rearwards. Thus, an accurate course of the implement along an intended processing path is obtained.
