KUHN Celebrates 40 Years of Slinger® Innovation

2024 marks the 40th year of the KUHN Knight Slinger® side-discharge manure spreader, a truly innovative mainstay of the manure handling product segment. The first Slinger spreader rolled out of the Brodhead-based Knight Manufacturing Company facility in response to the challenge of modern dairy farmers dealing with both slurry and solid material, providing them with one machine to handle all their spreading needs. The company further improved the Slinger spreader in 1993 by introducing the revolutionary ProTwin® twin-auger design to eliminate material bridging problems and ensure smooth, even delivery.

Knight Manufacturing Company was purchased by KUHN in 2002 and became the headquarters of Kuhn North America, Inc. This manufacturing facility and distribution center in Brodhead, Wis., builds and ships non-commercial SL 100 Series and commercial SLC 100 Series ProTwin Slinger manure spreaders to farm implement dealerships across the U.S. and Canada, along with export shipments to countries including Brazil, Japan and Mexico. These modern Slinger spreaders continue to perform with the same industry-leading quality and durability established 40 years ago.

Kuhn North America is celebrating 40 Years of Slinger Innovation with several promotional events and offerings throughout 2024, including a “Sling & Snap” photo contest, vintage-styled clothing items, and limited-edition SL 100 Series Slinger spreader production units featuring a Knight-era-inspired paint color and commemorative 40 Years of Slinger Innovation decal. More details for these promotions will be published here on the website,, and the Kuhn North America Facebook page.
