A working vehicle with traverse system, wherein, when a traveling mode is switched to a traverse traveling, switching valve means (53) is switched to feed a full flow of pressure oil from a hydraulic pump (41) to a flow divider (55), which controls the flow to allow a specified amount of flow to flow to a control valve for hydraulically operating device (56), the control valve controls only the pressure oil required for steering to allow oil to flow to the hydraulically operating device so as to operate the hydraulically operating device (33), which rotates both swing members (35) about a vertical axis (38) so as to steer both front wheels (3) through 90 DEG (degrees) after both front wheels are steered, a vehicle can run transversely in lateral direction by controllably rotating both front wheels and, when the traveling mode is switched to the traverse traveling, the misalignment of straight-ahead driving due to poor road surface condition and weight imbalance can be corrected easily by operating the hydraulically operating device slightly to steer both front wheels facing inward or outward through a smaller angle, whereby a specified amount of pressure oil can be fed through the flow divider to the control valve irrespective of the flow of pressure oil from the hydraulic pump.
