The proven Kuhn Krause 4400 packers pulverize clods, press down stones and eliminate air pockets in the soil, resulting in a superior seedbed to give your crop uniform emergence and even soil temperature right from the start. Kuhn Krause’s innovative use of massive 6 5/8" roller axles eliminate the need for troublesome middle gang bearings on Flex-Wing models and eliminates the skip in the tilled soil due to the space taken by the middle gang bearing.
