A round bale mover for attachment to either a tractor mounted front-end loader or a tractor three-point hitch for moving a pair of round bales. First and second bale teeth extend from a first end of the bale mover for supporting a first bale thereon. Third and fourth bale teeth extend from a second end of the bale mover for supporting a second bale thereon. The first and second bale teeth are selectively movable towards and away from the third and fourth bale teeth. The third and fourth bale teeth are selectively movable towards and away from the first and second bale teeth. The bale mover enables the first and second bales to be moved towards one another and moved away from one another.
