A work machine including a vehicle body, a traveling wheel, first and second steering members, an actuator, first and second operation sensors that output operation signals indicative of operation of the first and second steering members, and a controller. The controller acquires the first and second operation signals. The controller determines whether or not the first steering member is being operated, and whether the first steering member was operated last. The controller performs an automatic control of the actuator to set the steering angle to a target angle upon determining that the first steering member is not being operated and the first steering member was operated last. The controller does not perform the automatic control upon determining that the second steering member was operated last even if the first steering member is not being operated.
