A control device includes a bucket position-determining unit, a target working line-determining unit, a distance-determining unit, and a bucket control unit. The bucket position-determining unit determines a position of a bucket. The target working line-determining unit determines a target working line indicating a target shape of an object to be excavated by work equipment. The distance-determining unit determines a distance between the bucket and a reference position which is an end of the target working line. The bucket control unit controls the bucket such that an angle of the bucket becomes a uniform angle, when the distance between the bucket and the reference position is equal to or greater than a bucket control-limiting threshold value.
