Many Chinese and Japanese models are working in India, but these existing models could not become much popular due to some problems like planting more seedlings per hill, complex construction design and more cost. It has been proved an ergonomically, more plants lead to less production. The main aim of this research was to reduce complex construction design and improve accuracy of rice transplanter. Therefore a new transplanting mechanism model was developed for prototype single row rice transplanter. The transplanting mechanism was designed in solid work software after estimating the dimensions of the model using graphical method and then itwas fabricated. This model consists of three sub-assemblies such as transplanting assembly, seedling tray assembly, and main frame. It was tested in laboratory and measured different parameters such as depth of planting, number of seedlings per hill, hill to hill spacing and visible damage were found to be 5.55 cm, 2.3, 14.43 cm and 0.05 (out of 2.3 seedlings) respectively. After its satisfactory performance in laboratory, 17 Watt DC motor was fixed to rotate the four bar mechanism and tested in the field. The prototype single row rice transplater was tested in the puddled field of the size 2×1.5 m. Depth of planting, hill to hill spacing, number of seedlings per hill and visible damage were found to be 5.36 cm, 18.03 cm, 3.57 and 0.70 per hill respectively. From all these observation, it might be concluded that it was working satisfactorily and it will give an alternative way to design the transplanting mechanism for power operated rice transplanter and help to reduce complexity of constructional design up to certain limit.
