A high speed chaff cutter is a powered agricultural machine used for quickly cutting fodder crops such as grass, maize stalks, hay, and straw into small pieces for animal feeding. It operates using high-speed rotating blades driven by an electric motor, diesel engine, or petrol engine. It improves feed preparation efficiency, reduces labour, and produces uniform-sized chopped fodder suitable for livestock. It is commonly used in dairy farms, animal husbandry, and feed processing.
