Farm tools are implements of very simple nature which are commonly found with farmers who cultivate small farms. Farm tools, equipment and machines are classified according to the kinds of operation they perform on the farm, and the stage of cultivation at which they are employed. The usefulness and length of the useful life of any farm tool or equipment depend on the quality and proper handling of the implement. Since farm processes are necessary and delicate, farm implements are designed with great care and accurate specifications to adapt them for the uses for which they are intended. The farm equipment can be a simple mechanical device or a more complex device. Most farm machines require little or no manual operation because they are motorized. The necessary care of machines involves both regular maintenance procedures and the care to be taken when using the machine.
