ABSTRACT:
The invention is directed to a foldable agricultural implement frame having an extended working configuration and a folded transport configuration. The frame comprises a center section and two wing section. Each of the wing sections have row markers that are extended and retracted by a row marker hydraulic circuit. The row marker hydraulic circuit is provided with first and second supply/return lines each having a two-position latching valve. A mechanical linkage comprising a rod extends between the center section and one of the wing sections, for shifting the latching valves to their checked position, when the implement frame is folded from its working configuration to its transport configuration. The latching valves lock the row markers in their retracted transport position.
