This research focuses on the modification and performance evaluation of a battery-operated brush cutter, aiming to enhance cutting efficiency. modifications of a brush cutter Was carried out by replacing belt pully system with suitable size of gear box. Various motor speeds and blade types were used to evaluate the cutter's efficiency. The effects of blade type, motor speed, and cutting height on efficiency were assessed in field experiments, while laboratory tests evaluated for battery charging/discharging and motor performance under load and no-load situations. Field trials demonstrated that the three-point blade, operating at 9000 rpm with a 30 mm cutting height, achieved the highest cutting efficiency of 97.78 per cent and a uniformity coefficient of 97.49 per cent. The optimization analysis confirmed these parameters as optimal for the brush cutter’s performance. The results indicate that the modified battery-operated brush cutter is highly effective. The study concludes that the optimized brush cutter offers a promising solution for grass species such as Indian copper leaf, chickweed, Parthenium hysterophorus, and sickle pod grass, providing excellent cutting efficiency and uniformity performance.
