KUHN Knight RC 300 Series Reel Commercial mixers provide superior durability and performance with innovative options that separate them from the competition. Available in trailer, truck and stationary models, these mixers feature enhanced durability and operator‑friendly upgrades that boost efficiency, reduce maintenance and improve control helping operations save time, minimize wear and maximize productivity. For dairy and beef producers mixing rations with high percentages of roughages or distillers grains, this design gives them the ability to efficiently handle a wide range of materials. The RC 300 Series delivers smooth, consistent mixing thanks to its patented Helix® Reel, the only open-center reel on the market that allows unobstructed feed flow. Twisted reel arms further enhance this design, providing smooth running performance without load spikes. Working in tandem, the efficient reel and auger system reduces power draw, lowering operating costs, saving fuel and minimizing tractor horsepower requirements while still maintaining superior mixing performance. Built for longevity, the RC 300 Series incorporates heavy-duty drive and box components, with optional 304 stainless steel liners available to extend durability and provide years of reliable service. Feeding efficiency is also improved through a high-positioned discharge door that enables most operations to feed directly into J bunks with a simple slide tray, while optional conveyors add reach, deliver even feedout and minimize waste. To meet diverse operational needs, KUHN offers trailer, truck and stationary models, each customizable with augers and liners to ensure optimal performance across applications. Truck-mounted versions are available with mechanical or hydrostatic drives, offering operators straightforward functionality alongside advanced features that enhance overall efficiency and ease of use.
