History
WE MAKE IT RIGHT
Irrigation Accessories Co. has been manufacturing Ag Irrigation products for over 55 years. Bill Stout started inventing in the late forties and continued to do so until he passed in 1971. Formed in 1954 and incorporated in 1962, IACO supplied great service and the right product. That tradition continues today. Whether it’s supplying a dealer with replacement parts for a failed overseas knockoff, developing the Big Gun Pod™ automating handlines or continuing to develop Boombacks™ with products like the Hose Boom™ and Sling Finger™ for an evolving environment. We strive to make it right.
