During the cutting of crops, farmers face harsh climatic conditions such as summer (for cutting crops of wheat, sugarcane, corn, mustard, etc.), and winter (for cutting crops of rice, sunflower, herbs, etc.). It is a general observation that to avoid such harsh conditions of weather, the farmer used to cut the crop during the night (in summer especially) and sometimes face accidents such as snakebite, insect bite, or wild animal's attacks which lead to the death of several farmers. As manual cutting (i. e. utilising by manpower) takes several hours, sometimes a farmer loses his crop due to a sudden change in weather such as rain. There are various machines available such as harvester which consumes either conventional fuel (Diesel) or electricity which leads to air pollution. Hence, there is a requirement of a machine which consumes no conventional energy, saves both time and cost. To get rid of all, SEOCCM is conceptualized for providing a solution to the farmer who cut the crop manually or using a conventional source of energy. It is fabricated using a PV module (165 W-p), DC motor (250 W, 12 V, 4.2 A, 1500 rpm), cutter (diameter of 250 mm, tips of Tungsten Carbide), charge controller, battery (80 Ah) and iron frame. SEOCCM saves a conventional source of energy (e.g. fuel, or electricity) as it works on solar energy which is a renewable form of energy. The other features of SEOCCM include: (i) provisions for water bottle, (ii) meal, (iii) umbrella, (iv) LED light, (v) Insect rappeler (by ultrasonic sound waves).
