3. ABSTRACT . Grass cutter is a simple machine used for trimming down grass and maintaining fields and grounds from turning into forest. .Today for a cleaner and safer environment we are introducing electric grass cutters .It runs on solar power making it more cleaner, safer and eco-friendly .It uses solar panel to generate electricity and store them using batteries which drives the motor of the grass cutter. .Our machine reduces cost , time , manpower and is green and environment friendly 3

4. LITERATURE REVIEW . Overgrown weeds and grass where a problem ever since humans decided to build house and gardens. . first started to pull them out by hand ,then came simple tools and machines . Manual methods were later replaced by IC engines to reduce time and man power . They produces pollution and noise . They are also hard to maintain and repair. . our machine is eco-friendly , pollution free , use renewable source of energy , negligibly low maintenance , efficient and produce very less noise. 4
