India is an agricultural nation with the majority of its population residing in rural areas. The rural landscape is predominantly occupied by agricultural activities, including crop production and poultry farming by using of chaff cutter machines. The conventional cutter machines are unsafe design resulted in severe injuries and needed more workforces. Taking into consideration the limitations of the current conventional cutter machine, this project has been undertaken to develop and manufacture a chaff cutter machine, aiming to mitigate the potential for serious injuries and enhance operational efficiency. First of all, the work of design of the chaff cutter machine will be developed and analyzed. The new chaff cutter machine will be tried out for cutting various types of animal feed like dry straw, grass, corn straw, wheat stalk, etc. We'll also check how cost-effective the new machines are compared to the old-style ones and newer models. This paper talks about how we made and tested a chaff cutter machine in India. We'll also look at how much it costs to use the new chaff cutting machine compared to the old ones.

Dairy farming has become one of major sources of income for farmers. To maintain a large dairy farm, fodder must be available in palatable form at every point of time in sufficient quantity. To ensure that the ready fodder is available for cattle, a high-capacity chaff cutter is necessary. A high speed and hogh-capacity chaff cutter procured from the local market and tested for its performance. The machine consisted of a flywheel type cutter head which was mounted on the rectangular platform. The cutter head consisted of three rectangular plain knives fixed 120° apart on a circular disc of 440 ϕ. The feeding assembly was mounted with three feed rollers viz., upper, low, and additional. Chute type feeding mechanism was provided. The machine was operated by a 3.73 kW diesel engine. The ‘v’ belt was provided for power transmission from engine to cutter head with a reduction ratio of 1:0.32. Feed rollers were driven by bevel and spur gears. Short run and long run evaluation of the mac.

Generally in India large scale as well as small scale farmers facing the problems of labor shortage for crop cutting as well as collecting it. It takes the extra efforts and becomes more expensive. So there is a scope of forming a machine of such kind which is having average cost and able to minimize required time as well as labor cost meanwhile the available machines in the market are expensive. As this machine providing both cutting and collecting facility, it will be helpful to minimize labor charges.

India ranks first in the livestock population of 485 million as per livestock census (2008. Occasionally farmers chop the fodder into smaller sizes, using sickles or sharp knives for feeding the animals which may increase the utilization and digestion ratio. To meet the growing livestock farms demand, use of high efficiency, safe forage chaff cutters are the need of the hour. Traditional fodder chaff cutters are not suitable for fast and large scale chopping. The power chaff cutters alone could serve as alternative under present labour crisis particularly in India. Optimization of working parameters is highly essential in improving the efficiency of chaff cutters. Hence, a study was taken up to evaluate 'SwarajToka' make power operated chaff cutter under three speeds (0.1,0.12 and 0.14 m/s) with two different blades (Straight edge and Serrated edge) for para grass at different levels of moisture content(63.13%, 56.25 % and 51.3%) at College of Agricultural Engineering, Bapatla. It was found that the efficiency increased with the increase in cutting speed and moisture content. The maximum efficiency of 85.1 % was obtained at the maximum speed of 0.14 m/s at maximum moisture content of 63.13% whereas the minimum efficiency of 48.5% was obtained at the speed of 0.1m/s at a moisture content level of 51.3%. The efficiency was more in serrated edge of 85.1% than in straight edge of 66.4%. The maximum and the minimum capacity of chaff cutter obtained were 0.471 Mg h-1 and 0.309 Mg h-1 respectively. A maximum length of cut was observed to 2.24 cm at a moisture content of 51.36% and a minimum length of cut was observed to be 1.84 cm at 63.13% moisture content in case of serrated edge blade while a maximum length of cut was observed to be 2.52 cm and 2.24 cm at 51.36% and 63.13% moisture content of chaff for straight edge blade.Finally, it was concluded that the maximum efficiency of chaff cutter can be obtained at highest moisture content of Para grass, highest speed of chaff cutter with serrated edge blade and with an inverse relationship between chop length and moisture content.
