Farm mechanization is extremely significant in any country. An appropriate set of methods must be followed for the exact mechanism design. There are various approaches for designing mechanisms, but a correct methodology must be used for agricultural machinery mechanism design to ensure precision operations. Most farm machinery has four-bar systems. This study uses these principles to construct a four-bar system for optimal path planning. The motion for the tillage operation tool is provided, and a mechanism is designed and built with mechanical synthesis techniques such as graphical and analytical approaches. The synthesized mechanism is then simulated in MATLAB to see how it traces the motion trajectory with minimum error.
