This article tends to provide the design and development of MULTI-CROPS CUTTING MACHINES with manual or mechanical control. The current situation in our country, the traditional use of harvesting mechanisms is more tedious, time-consuming and is not able to develop the agricultural sector of farmers with low economic levels. Based on the problem stated through the abstraction of literature and existing reapers, to satisfy the needs of the client, the data was interpreted to meet the requirements of the problem objective. The idea was to create an inexpensive machine that would reduce the labor required to harvest crops. Small farmers can use this machine. This machine is compact and capable of cutting up to 2 rows of corn stalks, bajara stalk. It has a high-strength cutting blade that cuts crops in a rotary-type motion. It operates with a 3 HP motor, this motor power is supplied to the cutter through an arrangement of pulleys and gearboxes. A collection mechanism is provided to collect the crops on one side of the machine after cutting. There are some steps involved in making this machine, such as making the small model using suitable material and testing the working of this machine. The objective is therefore to manufacture and test the performance of a small model of manually or mechanically controlled grass trimmer for cutting crops. Cutting back crops quickly can allow more time to prepare the ground for the next planting. Say no to plagiarism. Get a tailor-made essay on “Why violent video games should not be banned”?

This harvester could be the solution to the problem faced by a small farmer regarding implementation and labor cost.IntroductionIn this modern world, the use of agricultural equipment is constantly increasing. India uses only 10% agricultural equipment, according to a survey conducted in 2012. India ranks second in agriculture. Agriculture such as forestry and fishing represented 13.7% of GDP (Gross Domestic Product) in 2013, or around 50% of the total workforce. The economic contribution of agriculture to India's GDP is continuously declining with the country's widespread economic growth. Agriculture is the most widely followed profession in India. Agricultural products contribute an important part to our economy. Engineering science has brought huge changes in the traditional methods of agriculture like sowing, planting, irrigation, fertilizer, spraying, harvesting, etc. However, to improve our economic situation, we must increase the productivity and quality of our agricultural activities. Nowadays, only a handful of skilled labor is available for agriculture. Due to this disadvantage, farmers prefer to use combine harvesters. These harvesters are expensive and are only available for very large-scale farming. However, agricultural groups use these available on an hourly basis forto rent out. But small farm owners generally don't need full-featured combines. Also, these combine harvesters are not available in all rural states of India due to financial or transportation reasons. There is therefore a need for a smaller, more efficient combine harvester that is more accessible and also considerably less expensive. This mission is to create a portable, user-friendly and low-cost mini harvester. Keeping in mind the requirements of the current situation, the idea was created to prepare a machine that is cheap and will reduce the labor required for cutting the crops. The requirement for this model is the demand for a compact and economical mower. This drawback is taken into consideration for this project. Considering the current corn harvesting scenario, we have decided to prepare a corn harvester model which will be suitable for farmers with small agricultural land. The prototype machine will be more economical and practical for cutting corn stalks and other similar plants with the same or lower shear strength as corn. Documentary survey Until the 19th century, most crops were harvested by sickle cutting. A sickle is a curved, hand-held agricultural tool, typically used for harvesting crops before the advent of modern harvesting machinery. The inside of the curve is sharp, so the user can swing the blade against the base of the crop, catching it in the curve and cutting it at the same time. In the early 20th century, animal-powered machines, called "combines", were developed to integrate the cutting, threshing and separating of wheat and small crops. A harvester was designed and manufactured at the University of Faisalabad in Pakistan. This was a self-propelled mower equipped with a 5 kW gasoline engine (without conveyor) which can harvest one hectare in 2.5 hours and is equally effective for forage crops as for wheat and rice. A tractor front mower was developed in 1980 at the Agricultural Mechanization Research Institute (AMRI), Multan, Pakistan. V-belt drive is used as the power transmission mechanism in this project. The mechanism is hydraulically operated via the 3-point hitch. The vertical conveyor mower was developed in the People's Republic of China. This was a mower equipped with an 8.95 kW diesel engine with a field capacity of approximately 0.65 ha/h. This is a motor harvester, walking type, suitable for harvesting corn stalks and bajara stalks. Grag et al. (1985) designed and developed a front-mounted vertical conveyor mower-swather with a cutting width of 1.9 m, operated by a tractor of approximately 25 hp, which could be harvested efficiently. Hadidi et.al (1984) stated that crop stubble height increases as stem moisture increases. the contents increased and decreased with increasing knife speed. He added that the percentage of wheat and rice grain losses increased as the forward speed of the machine increased. If we increase the speed of the cutter bar, it will result in a decrease in the percentage of grain losses. In addition, increasing the forward speed leads to an increase in the number of uncut stems. Sahar (1998) reported that the use of a large-scale machine is inappropriate for the following reasons: it requires high technical experience for its operation and maintenance, as well as high capital requirements. The use of small machines is appropriate for small farms, low capital requirements and lowtechnical experience in operation and maintenance. EI-sharigi et.al (1992) developed a front mounted mower. Design features included a flat belt mechanism transporting the crop to the side of the machine and an improved header star wheel assembly to minimize clogging. a bevel gear drive for power transmission, a sturdy frame, a commutator providing a design that will not sink into the ground and provisions to convert flat belt conveyor drives to chain without modification to the frame. Habib et al (2002) stated that the parameter effects on the cutting process are related to the cutting tool, machine specifications and plant material properties. They added that cutting energy is consumed during the harvesting process. Badr (2005) compared the performance of three different combine harvesters in terms of harvest time, grain losses, fuel consumption, energy required and total cost. It found that the highest field capacity is 3.02 acres/hr and the lowest field efficiency of 70.5% was obtained at a forward speed of about 4.0 km /h and a grain moisture content of 22%. D. N. Sharma and S.Mukesh, studied on handle design and in this study, a height of about 100 cm is enough to push any machine. DR.UV Kongre (2016) Introduction of a new type cutter which can reduce the dependency of workers, which gives great effect in maximizing the profit of farmers. The work was carried out with the aim of designing modifications and evaluating the performance of the manually operated mower. Imrul Kaes Mirza Kiran (2016) Bangladesh is predominantly an agricultural country, around 80% of the total population lives in rural areas and 95% of them are involved in agricultural activities. The world's largest delta is located between 88.01 and 92.4 degrees east longitude and 20.34 and 26.38 degrees north latitude. As the delta lands are very fertile and the climate is favorable for the production of cereals like paddy and wheat. So it is very important to harvest the crop timely. Crops risk failure if harvest is delayed. Labor shortage is felt during the harvest season as the time available for sickle harvesting is quite tedious and labor intensive. During the harvest period, labor is scarce and harvesting is normally delayed, leading to greater crop losses in the field. MethodologyPlanning: It is expected that as a solution to this problem, a mechanical weeder has been designed and developed to meet the current needs. requirement for weed control. Accordingly, the present development relates to improved manual control of plowing, mulching and weeding with low efficient operation, low working effort and high time requirement for different types of hoe and cutlasses which can be overcome through the use of a mechanical weeder. which are to be used in the machine should be designed like frame, handle, chain sprocket, blades, wheels and spring using the drawing software. Material Purchase: Once the component design is completed, the material should be selected and purchased as per the following properties required for our work. Selected Material (Mild Steel): AISI 1018 mild/low carbon steel has excellent weldability and produces a uniform and harder housing. It is considered the best steel for carburized parts. AISI 1018 mild/low carbon steel provides good.
