Self-Propelled Multi Tiller for Green Farming

Here, the design and performance analysis of a self-driven multi-tiller for small-scale and eco-friendly agriculture is described. The proposed system is designed to run on an electric power source with a voltage of 12V, utilizing multiple DC motors for both propulsion and tilling action. The design calculations involved estimating the total weight of the system, wheel loads, force of resistance due to soil cutting, torque for tilling, as well as the total power requirements for the system under loamy soils. From these calculations, appropriate motor selections, along with gear reduction systems, were made for shallow tilling. A factor of safety has also been taken into account for dynamic loads as experienced in practical agricultural applications. Results show the proposed design is mechanically robust, economical, and power-efficient, thus ideal for sustainable eco-friendly agricultural applications.
