Low Cost Mechanical Aid for Rice Harvesting

Ganesh C. Bora and Gunner K. Hansen    

Abstract: A small engine-powered harvesting aid for small area rice farmers was developed. The machine was a modified brush cutter. The original cutter blade was replaced by a 25 cm diameter circular saw blade. A metal plate and rubber guard assembly was fitted behind the blade on the handle to guide the cut stalk to the left side. The machine performed well in the field conditions with a field capacity of 0.51 ha day-1 consuming 0.25 L of fuel in an hour. It was 7.8 times faster than manual harvesting though the field loss was around 2.3% as against 1% in manual harvesting. The break-even area was 1 ha and the payback period for the investment was one year. The machine should be affordable to low income farmers in developing countries and women would also be able to taste the fruits of mechanization.
