In this paper, a four bar mechanism was designed for the specified performance output for a tractor. In tractor's plowing is engaged with the assistance of a hydraulic cylinder. Looking on the soil hardness the plowing depth fluctuates that isn't fascinating. To induce the correct plowing depth an Electrical control system is introduced. It consists of hydraulic valve, control unit and also the angular sensor. The control system helps to regulate the plowing depth accurately. The device measures the position of pivot and offers feed back to the system. Thus a sturdy, reliable and safe link mechanism is developed to measure the angular motion of the pivot. The main focus of this paper is to analyze Dimensional synthesis is performed supported Freudenstein's Equation and Chebechev's formula in Matlab and calculate the structural error of linkage mechanism by using Adams. Dimensional synthesis of 4 bar link mechanisms helps the designer to design link mechanisms with correct dimensions and simulation in Adams helps to optimize the link mechanism.
