Abstract:
This work machine comprises a vehicle body, traveling wheels, a steering actuator, an articulate actuator, an articulate angle sensor, and a controller. The vehicle body includes a rear frame and a front frame. The front frame is articulated to the rear frame so as to be moveable to the left and right. The steering actuator steers the traveling wheels to the left and right. The articulate actuator changes the articulate angle between the rear frame and the front frame. The articulate angle sensor detects the articulate angle. The controller executes automatic steering control for steering the traveling wheel automatically by controlling the steering actuator. The controller restricts the travel of the vehicle body or restricts the automatic steering control according to the articulate angle.
