Abstract
A motor grader includes an operation apparatus, a front frame, a draw bar swingably attached to the front frame, a first actuator attached to the draw bar, the first actuator moving the draw bar in a lateral direction with respect to the front frame, a second actuator attached to the draw bar, the second actuator moving the draw bar in a direction toward the front frame and a direction away from the front frame, and a controller that causes the first actuator and the second actuator to operate. The controller causes the first actuator and the second actuator to operate based on an operation signal received from the operation apparatus such that a position of the draw bar with respect to the front frame comes closer to a neutral position of the draw bar with respect to the front frame.
