The Kuhn Knight ProSpread® Commercial Series sets the standard for durability and versatility in the commercial box spreader class. The PSC 161, available in truck and trailer models, is designed for operators who need a high-capacity, heavy-duty machine to spread the toughest materials, including pen pack, feedlot/dairy manure, poultry litter, compost, bio-sludge and lime, as well as many other solid and flowable materials.

This spreader provides consistent performance, dependability and long life with its sturdy all-welded construction, friction-resistant poly floor and innovative split-apron drive. With three discharge options – horizontal beaters, VertiSpread® vertical beaters and AccuSpread® spinner discharge – these high-capacity spreaders will spread a broad range of materials. Save on fertilizer costs by combining the vertical beaters with an optional scale system to monitor application quantities and take maximum advantage of the nutrient value of your manure.
