Abstract
A work machine includes a vehicle body, a traveling wheel supported by the vehicle body, an actuator to change a steering angle of the traveling wheel from a neutral angle to left or right, a first steering member, and a controller. The first steering member is operable between a left steering range, a right steering range, and a neutral range. The controller controls the actuator so that the steering angle of the traveling wheel is changed to the left and right at speeds that correspond to operating amounts of the first steering member when the first steering member is positioned in the left and right steering ranges, respectively. The controller controls the actuator so that the steering angle returns to the neutral angle when the first steering member is positioned in the neutral range.
