ABSTRACT:
A wide farm implement is provided with a swingable tongue which permits endwise to and from fields. A pair of transport wheels are provided for supporting the implement for endwise transport and the support wheels, on which the implement is supported during a field working operation, are raised so as not to interfere with endwise transport. In order to prevent the automatic lowering of a row marker when the support wheels are thus raised relative to the frame, a blocking valve is provided in the row marker hydraulic circuit which moves to its closed position when the tongue is moved from its field working position thereby preventing lowering of the row marker.
