Abstract

Burning fossil fuel contributes to today's global warming, such as automobiles, gasoline-powered machines, and other carbon emission activities. Gasoline-powered lawn-cutting machines are known to be powerful, bulky, and heavy. However, they will cost the environment in the long run, aside from requiring high operational and maintenance costs. Hence, in this study, a battery-powered hand-held grass-cutting machine was designed and fabricated using commonly available materials and technology. Essential aspects such as durability, capacity, and weight were considered in the design for better performance. The battery-powered grass cutter has a 26.5V lithium carbon rechargeable battery, which drives the D.C. motor and can operate for up to 4 and half hours in the field. Thus, the generated torque will be transferred to the blade for efficient, less noisy, and vibration grass cutting. The entire configuration setup was mounted on a metal pipe and PVC pipe. This handy lawn-cutting device can be maintained and trim grass in gardens, flowers, homes, schools, or yards.
