actually we have a old goat power mill that was used to power old mechanical stuff on the farm long before my time, the mill we have was stationary the goat walked uphill and turned the drive chain, which basically acted like a pto you could hook stuff up to, my granddad always said his grandmother used it to power a washing machine and a big butter churn, and even had a old ice cream churn that would hook up to it a long time ago
all that is left now is the mill
