Farm Mechanization Mechanizing the rice production operations has often been a result of increased

drudgery when the task is done manually, the intensive power required in some operations like land preparation , the increasing cost of manual labor and the significant amount of time devoted to it (Table __), and the resulting quality of output when using tools or machines. Mechanization has always been associated with big or engine-powered machinery; however, it can also include the use of tools and devices to make field tasks easier and its completion faster. These tools could be in the form of hand hoes and carabao-drawn implements such as the moldboard plow and comb harrow that have proven very useful during the former years. Nowadays in the Philippines, mechanization is more associated with engine- or motor-operated equipment or field machinery, the most common of which is the hand tractor and the rice thresher.
