KUHN Knight VSL 200 Series Vertical Maxx® single-auger mixers are designed for small- to mid-sized dairy and beef producers. Two models, ranging from 420 to 550 cubic foot capacities (with extensions), offer the versatility of front, side or rear door unloading. The low-profile design is perfect for quick and easy loading. The proven cone-auger design reduces horsepower requirements, results in more efficient movement of feed and enhances final cleanoff of the auger when unloading.
