    Abstract: An improved hay bale spear implement comprises multiple spears and multiple support spikes extending outwardly from a frame. The arrangement of the spears and support spikes enables one or more spears and one or more support spikes to penetrate and support a single large round hay bale, two large round hay bales, or a large rectangular hay bale. The spears and support spikes may be positionable at various locations along the frame by a user of the implement. An attachment device couples the frame to a vehicle such as a tractor or loader. The attachment device may be removable from the frame to enable installation of a different type of attachment device to the frame.
