Petersen AG Systems

Petersen Ag Systems has been in business for 75 years and is known for quality service. Loyal and Gerald Petersen originally opened the company as Petersen & Son, Inc. Then in 1993 the company was purchased by the general manager and the name was changed to Petersen Agri Sales, Inc. Finally, in January 2000, the current owners purchased the business at which time it became Petersen Ag Systems, Inc. and was incorporated. The current owners are Henry Aschoff and Keith Wiehn. Henry is the President/General Manager and handles sales of grain bins and pivots and service. Keith is the Vice President and handles sales of Sentinel steel buildings and construction. Petersen Ag Systems currently has five locations, the main office which is in Osmond, a second in Norfolk, a third in Hartington, a fourth in Sloan, IA and a fifth location in Fremont. We currently employ 32 employees between all locations on a full-time basis and operate year round. We service and sell new and used pivots and grain bins, as well as steel buildings.
