Abstract
A work machine includes a vehicle body, a traveling wheel, a steering actuator, a leaning actuator, a leaning angle sensor, and a controller. The traveling wheel is supported by the vehicle body. The steering actuator changes a steering angle of the traveling wheel. The leaning actuator changes a leaning angle of the traveling wheel. The leaning angle sensor detects the leaning angle. The controller performs an automatic steering control that automatically steers the traveling wheel by controlling the steering actuator. The controller acquires the leaning angle. The controller limits travel of the vehicle body or limits the automatic steering control according to the leaning angle.
