SIOUX FALLS, S.D. — Two great agricultural companies are coming together to provide enhanced products for farmers. Copperhead Agricultural Products, based in Sioux Falls, S.D., will acquire RK Products, based in Moline, Ill., and founded by Phil Kester.

“Copperhead Agricultural Products first took notice of RK Products in 2015, since they adhere to the same high-quality standards,” says Jake Jass, Copperhead Agricultural Products sales & marketing manager. “Phil is a genuine engineer who always stands behind his work and is committed to helping farmers address wear issues with their corn planters.”

Since 2015, Copperhead Ag and RK Products have been working in partnership to expand the RK footprint so even more farmers can take advantage of their products. In 2018, after 20 years in the business, the Kester family made the tough choice to sell their company in order to focus on other areas.

“Copperhead Ag is excited to accept the challenge of growing the name recognition of RK Products and taking on the responsibility of manufacturing, selling and servicing their products,” Jass says.

Products that will be available under the RK product line include the gauge wheel arm pivot kit and the closing wheel frame pivot kit. The kits upgrade pivot and wear points on the gauge wheel arm and closing wheel frame. These kits, now offered by Copperhead Ag, provide an improved design to those components while repairing previous wear and significantly reducing future wear, without compromise.
