Pretty darn cool. The baler is not a great deal different than the old ram balers from the 19th century that ran off a belt from a steam engine and later a tractor. Cotton balers were like that as well, some with a hand operated screw press and others by steam powered ram. The rake works just like the old horse drawn hay rakes but those were pedal operated by a man riding the rake and a horse pulling it. My Dad had one that pulled behind a tractor that operated on a rope and boom a bit like yours does. How much do your bales weigh?
