Grass cutting is a time- consuming and labor-intensive process. The technology that is available in the present-day for grass cutting operation is mostly the manually handled Diesel operated cutter. These types of equipment operating under non-conventional sources of energy emit green- house gases and pollute the environment and also responsible for climate change. These grass cutters are also a source of noise pollution that adversely affects the health of the cutter and the surrounding people. The cost of diesel is another matter for consideration. To mitigate the problems of the conventional cutter, a solar-powered automatic grass cutter is designed. Solar energy is chosen because it is free of cost, pollution-free and renewable form of energy. The automation is done to reduce the need for labor. The design consists of a solar panel of rated power 20 W, Solar charge controller of voltage 12 V and current 10 A, sealed Lead Acid battery of 7Ah, 24 V high speed DC motor and cutter blades. Various sensors like ultrasonic and temperature sensors and microcontrollers are used for the automatic function of the machine. The paper summarizes all the design parameters, the working principle, design calculations on the basis of the solar radiation data of Guwahati city and also the cost analysis of the designed system.
