Abstract
A control device includes a bucket control unit and a speed restricting unit. The bucket control unit calculates a control speed controlling a bucket so as to maintain an angle of the work equipment at a constant angle. The speed restricting unit reduces the control speed when the bucket is driven at the control speed calculated by the bucket control unit and when a direction in which the bucket is driven and a direction in which the arm is driven coincide with each other.
