About Us

Sudenga Industries boasts a history spanning more than 133 years of Made in the USA pride. From its first days as a blacksmith shop run by German immigrant Folkert Sudenga, the company has developed, manufactured and sold durable ag equipment designed to make grain, seed and feed handling easier for farmers and commercial applications.


You’re not handed a reputation for service, innovation and durability—you earn it. And since 1888, Sudenga Industries has earned a reputation for providing the agricultural community with quality service and durable ag equipment for grain, feed and seed handling applications.

Sudenga’s product list includes portable augers, feed processing and automation systems, bucket elevators, drag conveyors, leg support towers and catwalk, round tube and u-trough augers, bin unloading systems including power sweeps and zero-entry sweeps for the commercial ag market, belt conveyors and a variety of accessories for installation of complete material handling systems.

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.
