Our History

King Ag Products, Inc. can trace its lineage back to central Oklahoma in the 1970’s. At that time, Richard Cox brought the portable feeder line to Carrollton, Missouri and grew the business from a start-up to a leading feeder manufacturer over 4 decades. In August 2013, Richard Cox Mfg. sold the manufacturing facility to King Ag Products, Inc. Since then, the company has continued to focus on high quality, low cost products for cattlemen across the Midwest, Southeast and Atlantic states. To understand the success of the business, one can look at the combined volume of portable feeders sales between the two companies: Over 60,000 feeders produced!!!

Not settling on one product, the company has launched three additional product lines in 2015/2016. They include mini stationary feeders, cake feeders, and portable/stationary bulk bins.
