We Deliver Greater Yields to American Farmers

Copperhead Ag Products was formed in the spring of 2009 after Dave and Todd Terveen, local farmers, discussed available closing wheels with Kevin Berg, a machine shop owner. They put their heads together and developed the Furrow Cruiser Spiked Closing Wheel — an option much different than any others on the market. After a few geometry changes to perfect the wheel’s closing action and the ability to slough off mud, the team began to show the product to local farmers. It was a hit! Marketing of the product began in the summer of 2009 to regional farmers, dealers and at farm shows. Copperhead Ag has since expanded into the Midwest region and beyond, with sales reaching to New York, Texas, Argentina and Switzerland.
