By compressing alfalfa stems completely, THE CRUSHER conditioning rollers help retain more leaves, significantly decrease dry-down time, and provides better nutritional value. Your chances of beating a rain shower are greatly improved. Balanced and trued to 1,000 RPMs, THE CRUSHER conditioning rollers operate without vibration. These rollers run in any style mower conditioner. We make new rollers for most makes and models. Thousands of these sets are in operation throughout North America and Australia. In side-by-side tests, our rollers have produced faster dry-down than comparable mower conditioners with factory-installed rollers.
