5. ABSTRACT
This project is to help small-scale farmers to meet an increased
demand for local grains, by designing a reaper machine to harvest grains
more efficiently. Our research work will focusing on ease of harvesting
operation to the small land holders for harvesting varieties of crop in less time
and at low cost by considering differentfactors as power requirement , cost of
equipment , ease of operation , field condition , time of operation and
climatologically conditions. The operating, adjusting and maintaining principle
are made simple for effective handling by unskilled operators.
Agricultural mechanization refers to interjection of improved tools,
implements and machines between farm workers and materials handled by
them. Independent India ushered in a process of agricultural mechanization
and revival of rural agro processing which got acceleration during post-Green
Revolution period. Irrigation pump sets, power threshers, tractors, power
tillers and matching implements, including for 65Million draft animals have
became popular.
Seed and seed-cum fertilizer drills, planters, mechanical rice trans
planters, vertical conveyor reapers, and combines soon followed. In the
recent past, Zero-till Drill and Raise Bed Planters have found good
acceptance from the farmers. Currently mechanization is in increasing
demand. Farmers and policy makers and developmental agencies now
realize that for increasing production and productivity at reduced unit cost of
production, free of arduous labour, agricultural mechanization is essential. It
is brought in centre stage with globalization of world markets.
Introduction of electromechanical power units supplementing and
substituting traditional animate sources of farm power is going to continue.
Shifts in agriculture leading to crop diversification towards horticulture, animal
husbandry fishery, forestryand on-farm agro-processing are going to bring in
greater degree of mechanization.
India dominated by small and marginal land holdings may not have
same trend of mechanization as the developed world but it is going to grow
close to it with its own variant as labour wages go up and WTO Competition
compels us to keep reducing unit costs of production,processing, packaging,
and retail and situations demanding provision of custom servicing, custom
agro-processing and acceptable standards of living.

6. The ultimate aim of agriculture or farming in India is not only limited to
growing of crops but is also associated with the economic growth of farmers
and labours. Small scale farmers frequently face the problem of labour
shortage or are unable to afford the wages to be paid.
These problems prevent the fiscal growth of farmers and ultimately
hamper the development of their farmland and family. Efficient, effective,
cheap and productive techniques are needed to strengthen the farming
community. This project is focused on developing a machine which
addresses labour problems faced by small scale farmers.
