A 3-blade chaff cutter is primarily used to chop up fodder, hay, straw, and other agricultural materials into smaller pieces. This process makes the feed easier for livestock to consume and digest, and also facilitates mixing and storage. The chaff cutter's blades are designed to cut through various types of fodder, including napier grass and maize stalks. The resulting chaff is easier for animals to eat, digest, and improves their overall health and production.
