This year’s featured engine line is the Associated Engine Line! The Associated Manufacturers Company produced reliable hit and miss engines during the early 1900s, helping power farms, workshops, and rural America before electricity became widely available. Built in Waterloo, Iowa, these engines were known for their simplicity, durability, and dependable performance. Farmers used Associated engines to operate pumps, washing machines, feed grinders, cream separators, and other important equipment. Today, these antique engines are admired for their distinctive sound, mechanical ingenuity, and the important role they played in agricultural history.
You’ll find a variety of historic engines displayed all across Heritage Hill Days — in the Power House Building, the Phillips Building, and speckled throughout the show grounds. Don’t miss the chance to see live demonstrations and experience these fascinating pieces of agricultural history in action June 19th & 20th!
