Abstract

The un-winder for hay bales has a frame having a pair of opposite arms, and a link bridging the pair of arms. One of the arms is to be drivenly mounted at least in part to a roof, particularly the roof of a barn. The other arm is provided with means to unwind a bale of hay. This enables unwinding a bale of hay in a barn particularly when space for unwinding is limited using a compact self-driven suspended un-winders for hay bales.
