<P>PROBLEM TO BE SOLVED: To provide a traveling vehicle such as a four-wheeler working machine equipped with a turn linkage control device which can plant a seeding in a proper position even if it is used for multi-row planting such as eight-row planting. <P>SOLUTION: The traveling vehicle comprises: a turn linkage mechanism which blocks or brakes a drive force of a traveling propelling body inside a turn in conjunction with a steering mechanism; a transmission-shaft rotation number detection means of the traveling propelling body; and a control device which repeatedly and intermittently controls a state that the traveling propelling body inside the turn is driven by driving the traveling propelling body inside the turn and a state that the drive force of the traveling propelling body inside the turn is blocked or braked by the turn linkage mechanism when the number of revolutions of the traveling propelling body inside the turn reaches a prescribed value or smaller in the number of revolutions of a traveling propelling body outside the turn which is smaller in the number of revolutions than the traveling propelling body outside the turn on the basis of the number of revolutions of the right and left traveling propelling bodies detected by the transmission-shaft rotation number detection means at the turn of a traveling vehicle body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
