PROBLEM TO BE SOLVED: To provide improved rolling control taking into consideration a state of a ground working device.SOLUTION: A working vehicle in which a ground working device 15 to be rolling-controlled is connected to a traveling vehicle body 1 comprises: a duty control type electromagnetic hydraulic valve which makes the ground working device 15 roll to the vehicle body 1 by using a hydraulic actuator; a rolling angle detector 32 which detects a rolling angle; a working state detection part 31 which outputs a state determination signal for determining that the ground working device is in an operation state or in a non-operation state; and a rolling control module 50 which drive-controls the electromagnetic hydraulic valve on the basis of the rolling angle and the state determination signal. |
