Abstract- A Paddy saplings transplanter is a specialized
machine used for planting paddy saplings[1] into the fields with less effort and with high efficiency. The model is designed in the PRO-E software so that we can get an idea about the dimensions, mechanisms and cost expenses. This model mainly consists of three main shafts which play a key role in planting the saplings. These shafts are attached with chain mechanism so that it can facilitate rotary motion transmission from shaft-1 to shaft-2. Later this rotary motion is converted into reciprocating motion with the help of a disc with eccentric hole. This disc is attached to the floaters with a link so that the floaters can plant the saplings. However, rice transplanters are considerably expensive for almost all small-hold farmers. The present work is mainly intended to manufacture a cost effective machine so that it will be on reach to the small scale farmers Key Words: Paddy Saplings Transplanter, Disc with eccentric hole, Rotary motion, Reciprocatory motion, Floaters, Cost effective.
Agriculture is the backbone of Indian economy. Though, with the growth of other sectors, the overall share of agriculture on GDP of the country has decreased. Still, Agriculture continues to play a dominant part in the overall economic scenario of India[4]
2. Need For Paddy Planter
1. Introduction India is mainly an agricultural country. Agriculture is the most important occupation for most of the Indian families. In India, agriculture contributes about sixteen percent (16%) of total GDP and ten percent (10%) of total exports[2].Over 60 % of India’s land area is arable making it the second largest country in terms of total arable land. Agricultural products of significant economic value include rice, wheat, potato, tomato, onion, mangoes, sugarcane, beans, cotton, etc. It takes 5,000 liters of water to produce 1 kg of irrigated rice. To plow 1 hectare of land in the traditional way, a farmer and his water buffalo must walk 80 km[3].

Transplanting is tedious and time-consuming. Planting laborers can suffer from back problems. Difficult to get enough labor at peak periods to plant on time. Difficult to maintain optimum spacing and uniform plant density, especially with random transplanting and contract labor. Low plant density with contract transplanting on area basis lowers yields. Possible Risk that in rain fed areas seedlings (especially of modern varieties) may get too old before rain falls and the field is ready to be planted.[5]
