Heartland Ag was opened in 1981 in Ames, Iowa and Grand Island, NE as company stores for Tyler Corporation of Benson, Minnesota. The major products that were sold and serviced by Heartland Ag in Iowa, Missouri, Nebraska, Kansas, and Colorado were Tyler pull type fertilizer applicators, Tyler fertilizer tenders, Ag Systems anhydrous toolbar applicators, and Ag Systems wagons and anhydrous tanks.

In 1992, Tyler Corporation purchased the flotation fertilizer application line from Mertz Co., and soon introduced a new full line of Titan flotation applicators, and new Patriot row crop sprayers. Heartland added these product lines to their customer offering. In a short time, both the Titans and Patriots became a standard in the industry. Heartland became recognized as being a leader in sales and service of custom application equipment. Due to the increase in sales and a need to better service customers in Missouri, Heartland opened a branch operation in Marshall, Missouri in 1995 which continues to service customers in the area today.
Case IH acquired Tyler Manufacturing in 1998 and named Heartland Ag as one of 11 exclusive distributors in North America for its complete line of specialized sprayers. Heartland Ag is the exclusive distributor of Case IH application products in Iowa, Missouri, Nebraska, Kansas, and Colorado. This new Case IH product line soon became a leader in the fertilizer and chemical application equipment industry.

Today, Heartland Ag is recognized as the leader in the sales and service of application equipment in Iowa, Missouri, Nebraska, Kansas, and Colorado.
