Improvement of grass cutting machine commonly used in Brunei

The study involved a design and fabrication of a prototype power source for the brush cutter in which the two-stroke cycle petrol engine was replaced by a rechargeable battery powered electric motor. It can operate faster than the existing one when cutting the grass due to instantaneous torque produced. It was operated continuously more than an hour with a full charged as similar to the existing design. However, the mass of the prototype is 1.9 kg higher than the existing power source and the rotational speed was lower due to lower motor capacity (400W). The substantial advantages of this prototype brush cutter are being less noisy and vibration while operating.
