Approximately 28% of world’s population is engaged in agriculture related activities. Around 935 million people have been found to be involved in agricultural activities, 2/3rd of which are from Asia alone. In India the agricultural and allied sector has a contribution of 15.9% to the GDP and more than 50% of the workforce is employed in the same (Planning Commission and National Sample Survey Organization (NSSO)). Mechanization of farming related activities in India stands between 40 to 45% as compared to that of developed countries which have achieved above 90% mechanization. It has been planned to increase the availability of farm power from 2.02 kW/ha (2016- 2017) to 4.0 kW/ha by the end of 2030. With better rural and urban electrification as well as solar infrastructure, there is a need for electric alternative to diesel/petrol powered farm machinery. As per the different agriculture censuses, 68%, 18%, 9% and 4% land holdings lie in marginal, small, semi-medium and medium scale farm categories respectively. The farmers having such small to average size holdings are unable to generate much income or profit through farming activities. Thus, their ability to invest in mechanized farm equipment is less due to high capital as well as maintenance cost. With this motivation, the electric tiller technology was designed and developed to address the small to medium scale farm operations such as tilling, weeding, water pumping, ridge making and material transportation. The developed electric tiller technology provides an electric alternative to the conventional ICE powered (petrol/diesel) tillers. The vehicle architecture of the electric tiller was designed so as to achieve better effectiveness during tilling operations using rotavator blades. The developed battery pack with casing and vibration dampers was designed to provide the vehicle’s center of gravity above the rotavator shaft for achieving appropriate weeding depth. The motor mounting flange and coupling was designed to address proper weight distribution and reduction in vibrations. The battery pack is easy to mount and un-mount, which facilitates the user to charge it at desired locations through fast charging or solar CSIR-Central Mechanical Engineering Research Institute M.G.Avenue, Durgapur-713209, WB based charging solutions too. The clutch-less operation and electronic thumb throttle makes the electric tiller, easy to use in the field. The handle is also equipped with electronic motor brake lever and reverse switch lever, which makes it easy to control the tiller during on road /off road applications. An MCB has been provided for switching the power supply on & off. Also a state of charge display has been installed to provide the battery voltage during no-load conditions. The rear hitch of the tiller is compatible with a wide range of implements such as ridger, plough and cultivators. Rotavator for tilling/weeding, iron wheel for ploughing attachments can be secured on the standard 26 mm hexagonal shaft. The power take-off shaft is directly coupled with the motor shaft to provide high speed operation with centrifugal water pump (2 in inlet and outlet). A trolley with seat can be attached to the electric tiller for material transportation purposes of up to 500 kg. The indigenously developed electric tiller is a 100% pure electric power weeder for small to medium scale farm operations.
