A Light Weight Solar Powered Lawn Mower

Mechanical Engineering

High effect of emissions of gases after the combustion of fuel and gradually increase in the cost of fuel has always been a huge problem for both environment and human being. Power consumption become more important .so it is very necessary to use renewable energy. This lawn mower was totally based on sun as an energy source, which is considered as a renewable energy resource, it is off very light weight and reduces atmospheric pollution too. The weight of lawn mower was around 5 kg, it can be easily portable, ease to use, even an unskilled person can also use it. The fabrication of light weight solar powered lawn mower comprises of following components namely- a (50 Hz, 1 HP Dc Motor), (12V,7.0AH Rechargeable Battery), (Stainless-steel blade 0.8T), (On-off Control Switch) and (Solar Panel). The lawn mower has a 360-degree rotating panel arrangement in such a way that it can receive a high intensity of solar radiation from sun. The solar panels convert solar energy into electrical energy, the electrical energy get stored in a rechargeable battery. when switch is on, circuit get closed and it allow the current to flow in the dc motor, the dc motor can be adjusted to considerable length it can be manually adjusted up to 5 cm, the supply of power from the battery is given to the dc motor, the shaft of dc motor start rotating with which stainless steel blade is coupled, which has very sharp edge it also starts rotating with the shaft and cut the grass at an even length.
