Agricultural Mechanics and Technology Systems presents focused, technically accurate coverage of all major skilled trade disciplines in agricultural contexts, including construction, electricity, welding, and power systems. In addition, the text provides a wealth of information and resources on careers in agricultural mechanics and promotes a deep understanding of supervised agricultural experiences (SAEs) and career development events (CDEs). The second edition has been updated with over 500 new images and 35 new Career Connection features to portray up-to-date tools, technologies, and career opportunities. A chapter on Precision Agriculture and Emerging Technologies introduces students to the many high-tech applications, including geographic information systems (GIS), telematics, sustainable energy sources, precision agriculture, wireless sensor networks, and the use of drones.
