Back in 1950, Robert Dethmers started Dethmers Manufacturing Company in a corner of an implement dealership. One of his first products was fertilizer application equipment for the agricultural industry.

Today, as Demco continues to grow, our tradition of building quality products, employing talented, industrious people and providing attentive service remains. Our sales staff along with our dealers and distributors across the United States, Canada and the world carry on the standard.

Meeting the challenges and opportunities of changing times has produced growth in product lines. Our products are engineered and constructed with the best of materials and the latest in manufacturing technology, then tested beyond recommendations, pushing the product to its limit before the

Demco name goes on. Our reputation was built on quality and dependability and we continue by being tougher on the product than the consumer. Demco is committed to give its customers quality products tailored to meet their needs.
