Development of an Electric Power Weeder for Sustainable Agriculture

A power weeder is an agricultural machine used to eliminate unwanted weeds that hinder crop growth. Traditional models rely on internal combustion (IC) engines which cause pollution vibrations and high maintenance costs. To overcome these issues an electric weeder has been developed operating on battery power as a sustainable alternative. Mechanical weeding is preferred over chemical and manual methods due to its effectiveness. The electric weeder replaces the IC engine with a motor and battery reducing environmental impact and maintenance costs. Its system includes a frame motor battery controller and blades designed based on commercially available weeders. Structural integrity is analyzed through stress strain and deformation tests. Results show that the electric weeder is efficient cost-effective eco-friendly and user-friendly. It successfully reduces pollution and vibration while maintaining high performance making it a viable replacement for traditional IC-engine-powered weeders.
