During operating tractor create lot of vibration under and over land. This all kills earthworms of fertile land and as all you know earthworms is main factor to maintain fertility of agriculture land. So as a Farmer we only adopt traditional and natural methods of agriculture to pounding and convert Paddy into Hand Pounded Rice for you.
