Based in George, Iowa, in the northwest corner of the state, the Sudenga family became known for innovative thinking and reliable solutions. They produced a trip hammer in 1898, which was the first item to be “forged in George.” In the early 20th Century, they were one of the first Ford dealers in Iowa, an entity that split off from the smith shop.
By the mid-1940s, the descendants of Folkert Sudenga had made a very successful rear end loader that led them to focus on ag equipment manufacturing in 1946. Augers and other labor-saving farm devices followed. In 1962, it became Sudenga Industries, and in 1976, the last of the Sudenga family retired, selling the business to five key employees. The business survived the turn of two centuries, the Great Depression, several fires and the Farm Recession, and the products are designed to stand the test of time, as well.
