<p>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). The flow divider controls the flow to allow a specified amount of flow to flow to a control valve for a 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 a hydraulically operating device (33) to rotate both swing members (35) about a vertical axis (38), thereby to steer both front wheels (3) through 90 degrees. After both front wheels are steered, a vehicle can run transversely in lateral directions by controllably rotating both front wheels. When the traveling mode is switched to the traverse traveling, misalignment of straight-ahead driving due to poor road surface conditions 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. A specified amount of pressure oil can be fed through the flow divider to the control valve irrespective of the flow of the pressure oil from the hydraulic pump. <IMAGE></p> |
