Abstract: Facing the longstanding problems existing in the development of the precision planter such as the prolonged production period, the high production cost and the difficulty in the final assembly because of the interference between the interacted parts, a process of the virtual manufacturing and motion simulation of the precision planter unit was introduced applying the Pro/Engineer software. The final assembly of the planter unit was formed by restricting and connecting its parts 3D models. Its motion simulation was performed to demonstrate the movement characteristics in the virtual environment. The simulation results were processed to check the movement characteristics of the planter and to correct the possible interferences. The results showed that the proposed process improves the accuracy and efficiency of the precision planter design and deduces the development cost by using the virtual space instead of the physical space.
