ABSTRACT This invention relates to a transport wheel assembly for a tillage type agricultural implement having at least two pairs of ground support wheels mounted on the frame section of the implement. Each wheel of the pair is journaled in a separate axle mounted on the end of a pivot arm with the pivot arms being mounted in spaced shafts journaled on the implement frame. The shafts are separated longitudinally of the implement frame or across the width of the same to space the wheels longitudinally apart, and they are also separated in a fore and aft direction of the implement frame. The shafts of each pair are tied together through a hydraulic actuator which acts as a linkage to transmit motion from one wheel to the other when the implement traverses uneven terrain. The actuator in one position pivots the wheels in close proximity in the fore and aft direction for stability in turns and raising the implement and hence the ground working tools above ground level for transport. In the opposite position of the actuator, the implement frame is lowered for working and the wheels are separated in the fore and aft direction to a wide extent for greater stability in traversing uneven terrain. In the transport position, a strap ties the actuator to a fixed position for safety purposes. Stops on the frame limit movement of the transport wheels for stability purposes. On wing sections of the implement, the transport wheel assembly includes an adjustment of the wheel position for depth adjustment of the tools.
