Seedlings transplanting is a labor intensive operation in the production of rice. It is also technically a skillful job and involves working with a stooping posture in a puddle field for several hours, and a need should arise to mechanize this system. For this purpose, assessing rice transplanting technologies has been done to modify for the rice potential area that suit the need of the farmers, hence reviewing previous studies of rice seedling transplanting techniques and selecting of a six row manually operated rice seedling transplanting technology and important data’s on rice production process was collected, field visit on the study area were conducted, the path generated by the mechanism was plotted on a computer screen using AutoCAD software. A different model of transplanting machines and their mechanisms was assessed. Based on this, the design of planting mechanisms was carried out using the method of analytical synthesis based up on graphical synthesis. A four-bar linkage with coupler extension was selected as the basic design. By varying the dimensions of various links in the mechanism, different paths of output motion of the coupler point were obtained. The potential link dimensions were identified based on the suitability of the path for picking, conveying and planting of seedlings as well as the return motion. Conventional lathe, milling, pedestal grinding, drilling, arc welding and polishing machines were used to manufacture the machine. A two row transplanter using the above mechanism and an optimized planting finger was then developed. The pilot wheel for the proper positioning and guiding of the transplanter machine keeping the mat stable was introduced that additionally enables the fork to put the seedling in the recommend depth at different hills. Generally, the machine transplanting system is found to be technically viable.
