Abstract: The increasing demand for environmentally sustainable technologies has encouraged the development of solar-powered grass cutting machines as an alternative to conventional petrol- and electricity-operated grass cutters. Traditional grass cutters contrib-ute to fuel consumption, greenhouse gas emissions, noise pollution, and high operating and maintenance costs, creating the need for cleaner and more energy-efficient solutions. This review paper presents a comprehensive analysis of recent studies published between 2020 and 2026 on the design, development, fabrication, and performance evaluation of solar-powered grass cutting machines. The review was conducted through a systematic examination of selected peer-reviewed journal articles focus-ing on machine design, component selection, working principles, fabrication techniques, and performance characteristics. The reviewed studies reveal that most systems employ photovoltaic solar panels, rechargeable batteries, DC motors, rotary cutting blades, and lightweight chassis to achieve efficient, economical, and environmentally friendly grass cutting. The findings demonstrate that solar-powered grass cutters effectively reduce fuel dependency, operating costs, maintenance requirements, and environmental pollution while providing satisfactory cutting performance under suitable solar conditions. However, the review identifies significant research gaps, including limited battery backup, reduced efficiency under low solar irradiance, inadequate optimization of blade and chassis design, and insufficient long-term field performance evaluation. Addressing these challenges can improve system efficiency, reliability, and the practical adoption of sustainable solar-powered grass cutting technologies.
