India is an agrarian country where livestock plays a crucial role in rural livelihoods. Efficient fodder processing is essential to ensure optimal feed utilization and minimize wastage. Traditionally, fodder is chopped using manual tools such as sickles and axes, which are labour-intensive, time-consuming, and result in non-uniform cutting. To overcome these limitations, the present study evaluated the performance of a power-operated chaff cutter powered by a 2 hp electric motor (1425 rpm, 230 V) for selected green and dry fodders, namely paddy straw, wheat straw, green grass and maize fodder. The results showed that fodder properties significantly influenced output capacity and chaffing efficiency. The output capacity was 142.5 kg/h for paddy straw, 140.7 kg/h for wheat straw, 174.05 kg/h for grass, and 326 kg/h for maize straw. The efficiency was 88.72% for paddy straw, 82.08% for wheat straw, 89.27% for grass, and 92.67% for maize fodder. The average length of cut pieces was 7.2 mm, 6.69 mm, 9.8 mm, and 8.4 mm for paddy straw, wheat straw, green grass, and maize, respectively. The operational cost was estimated at ?71.8 per hour, making the machine economically viable for small and medium-scale farmers. The study concluded that the power-operated chaff cutter reduces labour, ensures uniform fodder size, and improves fodder utilization efficiency compared to manual methods.
