Abstract

In recent years, the need for efficient and environmentally friendly gardening tools has increased, encouraging innovation in handheld grass cutters. This project investigates the design, development, and optimization of a handheld grass cutter with the goal of improving user comfort, lowering environmental impact, and increasing cutting performance. The proposed device combines a lightweight, ergonomic design with sophisticated battery technology and precise cutting mechanics. A high-torque, low-noise engine, customizable cutting heights, and a blade system with improved safety are among the key characteristics. The project takes a user-cantered design approach, incorporating feedback from extensive field testing, to guarantee that the cutter fulfils the different demands of both household and professional users. The final prototype improves efficiency, durability, and user happiness significantly thanks to a combination of technical research, material selection, and sustainable production processes. This handheld grass cutter concept not only advances garden maintenance tools, but it also promotes sustainable practices by reducing carbon emissions and energy use.
