Solar power energy from the sun is converted into thermal or electrical energy which is the cleanest and most abundant renewable energy source. The U.S.A. has the richest solar sources in the world. Solar energy plays an important role in agricultural operations like drying food products, solar water and air heaters, solar cookers, irrigation, street lights and some home appliances. In Indian farms, the cutting operations are mainly performed by hand. Now a days, the use of mechanized cutting instruments, powered by fossil fuels can also been seen in some places. In hand cutting, the cutting of the crops consumes ample amount of time and labour charges, which is a drawback.
In mechanized cutting methods, the operating & fuel cost of the machine exceeds the budget of a common farmer. To overcome all these drawbacks, we can use renewable, Non-conventional energy source like solar energy as it is easily available in nature. An application of non-conventional, renewable energy source is the alternate solution for current energy demand. In this project solar energy is used which is non-conventional-renewable energy source which is freely available, to reduce the overall cost of the cutting operation. The mechanisms used are also simple. The machine is light weight & Compact. Most importantly, can be easily availed by the farmers.

The global technical market’s demand trend for high strength, high performance, better quality, reduced cost and reduced weight materials has led to an emerging development in research and utilization of composite materials over conventional monolithic materials in various industrial applications. Aluminium –graphite composite has been developed by stir casting technique. Al-Graphite composites having 2%, 4%, 6%, 8% of pure aluminium is prepared. Tensile strength, Hardness test, Impact strength as a function of graphite performs and metal matrices have been determined. The tribological properties were varied significantly with addition of solid lubricant-graphite. The hardness test of composites is carried on Brinell hardness Tester and tensile strength is measured using a Universal testing machine and Charpy and Izod tests are conducted to find the impact energy. Around 15% increase is observed in the hardness of the composite compared to the hardness of pure aluminium and no significant increase is found in the impact energy of the composite, but more than 21% increase is found in the tensile strength of the composite.Keywords
