Mechanical weeding is one of the non-chemical methods to control weeds. In this paper a new mechanism has been presented for mechanical cultivation. The machine works based on the manual tools operation, which farmers still use in small scale for weeding and consists of a number of four-bar linkage mechanisms. Each mechanism consists of a blade which moves forward (active course) and backward (passive course). The three precise position methods were applied to design the mechanism. The Matlab software was used for solving the equations and drawing the path of motion. Considering the parameters and solving the equations, a four-bar linkage (crank-rocker) was proposed.
