Hand operated Chaff-Cutter

Agriculture in rural and semi-urban areas largely depends on simple and cost-effective tools due to limited access to electricity and modern machinery. Chaff cutting is an essential operation in animal husbandry for preparing fodder in manageable sizes to improve digestion and reduce wastage. This project presents the design and development of a handle operated chaff cutter, which functions without the use of electrical or fuel power. The machine operates on manual mechanical energy transmitted through a hand-crank mechanism, which drives the cutting blades mounted on a rotating shaft. The device is constructed using readily available materials, making it economical, easy to maintain, and suitable for small-scale farmers. The design focuses on safety, portability, and efficiency while ensuring uniform cutting of fodder such as straw, grass, and dry crops. Performance evaluation shows that the handle operated chaff cutter provides sufficient cutting efficiency with minimal human effort, making it an effective alternative to motorized chaff cutters in areas with power constraints. The project promotes sustainable agricultural practices by reducing dependency on non-renewable energy sources and supporting eco-friendly farming solutions.
