<P>PROBLEM TO BE SOLVED: To provide a turning/interlocking control type work vehicle allowing response to abnormal conditions without being forced by a troublesome operation such as release of automatic down control when operation in response to an abnormality such as correction of a turning position of a machine body becomes necessary before re-operating a ground implement by variations in field conditions, traveling conditions, and others. Ž<P>SOLUTION: The turning/interlocking control type work vehicle includes the ground implement (R) loaded so that changeover to an operating height and a turning height can be carried out, and a control part (21) for performing automatic lift control for changing over to the turning height in response to the start of turning of the machine body and automatic down control for changing over to the operating height in response to the completion of turning for the ground implement (R). The control part (21) performs the automatic down control as far as the position of the machine body after starting the turning is within the range of prescribed starting positions of the ground work, and the traveling vehicle speed of the machine body is similarly at a prescribed speed or above.
