Abstract - The conventional method of planting and growing crops is a laborious process, and therefore there is a shortage of manpower, resulting in a delay in agriculture operations. In this work, semiautomatic mechanical cutter was developed and fabricated by using 4 bar mechanism for cutting agricultural products like sugarcane bud and forage. The agriculture cutter was simple in construction than the existing machines and affordable to farmer and also save the time. The newly designed agriculture cutter was subjected to performance evaluation. Parameters such as cutting effectiveness were measured by calculating the number of buds feed and no of buds loss. Average cutting effectiveness of agriculture cutter was somewhat low (93.90%) as compared to mechanical cutter (94.33%) with less bud loss of sugarcane per lot during cutting.
Multipurpose agricultural cutting equipment can be designed based on the four bar chain mechanism. It is a much preferred mechanical device for the mechanization and control of motion due to its simplicity and versatility. Basically, it consists of four rigid links which are connected in the form of quadrilateral by four-pin joints. When one of the links is fixed, it is known as a linkage or mechanism. Link that rotate complete revolution is called the crank, the link opposite to the fixed link is called the coupler, and the fourth link is called the lever or rocker if it oscillates or another crank if it rotates. Prices of semiautomatic and automatic cutters (1 HP) commercially available in the market ranges from Rs. 21,239/- to Rs. 35,800/- and prices of manually operated chaff cutter ranges from Rs.6800/-to Rs.12900/-. While prices of manually operated sugarcane bud cutters ranges from Rs. 1500/- to Rs.1600/-.
Key Words: Agriculture cutter, 4 bar mechanism, sugarcane bud, cutting effectiveness.
1. INTRODUCTION
Due to high initial cost of existing chaff cutter and sugarcane bud cutter, low build quality of local brand cutter and does only single function, it is required to develop and fabricate the simple semiautomatic mechanical cutter using four bar mechanism affordable to farmer for cutting agricultural products like sugarcane bud and forage.
Agriculture plays a vital role in the Indian economy. Over 70% of rural households depend on agriculture. Agriculture is an important sector of the Indian economy, contributing approximately 8.4% to the total GDP and providing employment for over 60% of the population. Indian agriculture has experienced impressive growth over the past few decades.
2. MATERIALS AND METHODS The survey was conducted in different regions of the solapur district to collect information regarding land holding, types of crops cultivated, types of cutter used, problems faced by farmers in existing cutter, and improvement required in existing cutter. Agricultural cutter was fabricated using 4 bar mechanism and Performance of cutter was evaluated in terms of cutting efficiency, cutting capacity per hour, bud loss per hour and compared with traditional cutter.
Average land holding capacity of farmer in India is 1.08 ha and it can feed up to 8 persons. But the land holding capacity is decreasing day by day with increase in population. The conventional method of planting and growing crops is a laborious process which leads to shortage of manpower for other agriculture operations also. Agricultural cutting equipment is the basic and main equipment involved in agriculture for maximum performance. At present, there are different types of cutters available that can be categorized into various groups based on their technology, working mechanism and the crops they are designed to cut. In terms of technology cutters can be classified into autonomous, semi-autonomous and manually operated. Regarding their working mechanism cutters can be grouped as crop cutter, chaff cutter, sugarcane bud cutter, reaper binder, forage cutter, and lawn mower. Lastly, cutters can also be categorized based on the type of crops they are designed to cut such as sugarcane cutter, paddy cutter and rice straw cutter.

2.1 Working principle A four-bar linkage is a mechanical linkage of frame, rocker, connecting rod and crank connected by joints or pivots. It forms a closed loop and exhibits a motion. It can be used in various machineries and robotics to achieve controlled rotating or oscillating movements. 2.2 Development and fabrication of agriculture cutter Agricultural cutter was fabricated using MS strips (25mm width and 4mm thickness), bearing (to support rotating
