ABSTRACT
Tillage is the mechanical manipulation of the earth surface for providing favorable conditions for crop production. Mechanization of farm operations has become very necessary and the methods for reducing the power consumption have to be found out. This paper deals with factors affecting the tillage operation and the effects of the tillage operation on soil. Tillage implements usually produce large amount of vibration but providing a vibration to the implement reduces the draft force. Considering the performance of tillage tools, the main factors to be considered are its draft torque and power requirements. These tillage tools affect the properties of the soil in which it is working. This may be even cause degradation of the properties of soil. Another important factor is wear, which is the major cause of failure in tillage tools. Thus, studying the various factors, the best tillage tool may be selected or methods of reduction of power consumption may be identified.
