In advanced farming system the land preparation is done by means of rotating mechanisms as rotary tillers. A rotary tiller, also known as a rotavator, is a motorized cultivator, popularly used to decrease the total time and human efforts in soil preparation. It can incorporate every kind of crop residue into soil mainly to improve soil organic health. However, under dynamic loading, rotavator blades are subjected to abrasive wear, especially in sandy soil, which significantly affects its working life. This book, therefore, provides the solution to enhance the useful life of the rotavator blades in order to decrease the idle time required to reinstate the blade periodically during soil preparation. The objective was carried out by means of hard coatings, where the effect of the coatings on the extent of wear and the wear characteristics of the rotavator blades were examined. The wear rates of the coated blades were significantly lower than those of the uncoated blades, indicating a great improvement in the wear protection provided by the coatings.
