This is a pair of primitive iron cow hobbles, also known as cow kickers that were used to restrain uncooperative cows during milking. A cow cannot kick staight backwards, so by standing directly behind the cow these kickers could be slipped over the back of the legs, just above the hocks. An item like this was standard equipment on every farm with milk cows, during the early 1900s. The kickers have a patina of age and the surface of the iron is rusted. They are adjustable, by moving the chain through the slot in the curved iron hooks that rest just above the cow's hocks. You could enjoy adding this great primitive item to your collection and it would make a wonderful decorator piece!
