Our Roots

 The Knuppel family has been in the grain bin business since the early 1960’s. Ken's Dad sold new Superior bins and moved used bins in central Illinois, Ken began helping his dad with bin construction at age 4. In 1994 Ken and Martha, along with Ken's Dad, began business in partnership in Jacksonville, Missouri which later became known as Knuppel’s LLC.  The business consisted of buying and selling used bins and relocating bins for customers.  A typical year at that time would be to put up, or relocate 85-90 bins per year.  Ken says it was the best possible education for a career in the bin business as he got to work with all different brands of bins, all different manner of floors, stirring machines, grain spreaders, unload systems, etc.  “I got a chance to see how things were put together and what did and didn’t work.To this day when a customer calls me and describes what he has and what he needs, I don’t need a book- I can visualize it, and know how it is put together.”  In 1998 Knuppel's LLC began selling new GSI bins, M-C dryers, and Sukup grain handling accessories.  Later, in 2001, when Sukup Manufacturing  began manufacturing grain bins, Knuppel’s LLC became a charter bin dealer.  Knuppel’s LLC continued doing business through 2006. In 2007 Ken and Martha Knuppel formed Grain Bin Supply Company LLC, where they continue to provide quality Sukup grain bins and grain handling equipment, and a host of other products, service and construction.
