A stop control unit carries out control, when a moving speed of a bucket in a direction toward target design topography is the same in both of a first specifying state in which a bucket weight specifying portion specifies a weight of the bucket as large and a second specifying state in which the bucket weight specifying portion specifies a weight of the bucket as small, such that the moving speed of the bucket in the direction toward the target design topography is reduced from a position more distant from the target design topography in the first specifying state than in the second specifying state.
