An attachment for an industrial or farm vehicle is designed to engage, carry and unroll a round hay bale. The attachment can be adjusted to interact with hay bales of various lengths. The attachment includes a support structure with features to attach to the vehicle. A first end of a first arm is pivotably connected proximate a first end of the support structure. A first end of a second arm is pivotably connected proximate the first end of the support structure. A spacing link is pivotably connected to second ends of the first and second arms. A first hay bale spear is attached to the spacing link. A third arm has a first end pivotably connected proximate a second end of the support structure. A second hale bay spear is attached proximate to a second end of the third arm and faces toward the first hay bale spear.
