An assembly on an agricultural implement, especially a semi-plow, wherein the assembly comprises a plurality of pivotable and mutually interacting parallelograms and a plurality of partially interconnected link members (12, 26, 31, 34, 41) which regulate the implement's support wheel (22) and a turn limiter (44), whereby the turn limiter (44) is automatically regulated when the implement is being adjusted to adapt it to the tractor track as well as to the desired plow strip width so that the maximum angle of deflection, to the right or to the left, between the tractor and the turn limiter (44) is held constant no matter what the angle assumed by the implement in relation to the driving direction, said turn limiter thus preventing the tractor from abutting against the implement when the tractor turns sharply, while at the same time the wheel (22) is automatically correctly adjusted when the implement is being adjusted to adapt it to the tractor track and the desired plow strip width, whether the implement is driving in a straight line or on a curved path. |
