You don't need one of those to unroll round bales. I remember watching the ranch hand at the WVU equestrian center when she was competing between colleges. They simply took a round bale to the top of a hill (with cows flowing) cut the binding and let the bale roll down the hill! It was the funniest thing I had ever seen as the cows chased that roll down the hill!:laughing: Of course if they would have just stayed at the top they could have started eating and kept eating till they got to the bottom, such is the reasoning of a cow!
