A support frame of the ground-engaging farm implement has a front end portion which is adapted for being coupled to a hitch of a power unit. At least one ground-engaging tool is mounted to the support frame. A substantial portion of the weight of the farm implement is supported by at least one support wheel. A wheel support structure having the at least one support wheel rotatably moveable mounted thereto is pivotally movable mounted to the support frame such that the at least one support wheel is enabled to substantially vertically move a predetermined distance with respect to the support frame. A suspension air bag or the springs of a suspension system are interposed between the support frame and the wheel support structure for controlling the vertical movement of the at least one support wheel, enhancing ground contact of the tool and allowing for increased groundspeed of the implement.1/8 86 0=
