A grass cutter is a machine that is commonly used to cut grass in agricultural fields as well as private or public lawns. A grass cutter is generally used in agricultural fields to remove weed grasses, which grow naturally along with the agricultural crops and weaken the crop by absorbing all the water, pesticides, and other organic matter fed to the original agricultural crop. A grass cutter, on the other hand, is used for maintenance in both private and public lawns. When a farmer tries to remove the weed grass manually, they are prone to cutting their hands and bleeding due to the sharp edges of the weed grass, and they also suffer a lot from body itching. Farmers usually cut a type of grass called Axonopus compressus to feed the cows. They are again exposed to the same threats. So, in order to help the farmers and make their work easier, we developed a prototype of this weed and cow grass cutting machine. The grass cutter can cut grass such as clover to a short height; therefore, it can also be used for lawn maintenance. Unlike conventional grass cutters, which usually run on diesel or electricity, this one is powered by solar, which makes it more economical and eco-friendlier. The 3-D model of the project is made using SolidWorks®, which is a parametric software with a high user interface. The parts of the grass cutter, like the blade, battery, solar panel, motor, base frame, and wheels, were designed individually and assembled in an assembly line. The simulation in Simulink© helps determine the performance of the panel. Using Matlab© and Simulink©, a detailed model of the system has been constructed and developed. A simulation is run with a 100 W PV module, taking into account various irradiation levels. The obtained simulation results provide a detailed comparison of the performance of the converters in PV applications with the goal of extracting the maximum amount of power. In this study, a comprehensive comparison of the performance of several DC/DC converter topologies has also been conducted. The efficiency of both the Maximum Power Point (MPPT) and the converter is significantly enhanced by different irradiance changes. At standard test conditions, the boost converter delivers 85.2 W of power to the load, whereas the maximum power extracted is 92.5 W. Here, MPPT efficiency is 85.2 % and converter efficiency is 92.1 %. Consequently, system effectiveness is 78.5 %.
