Agricultural Machinery and Equipment

Agricultural Machinery and Equipment is a specialized area within agricultural engineering that focuses on the design, development, operation, and maintenance of the mechanical devices used in all phases of food and fiber production. This includes a vast range of tools, from tractors, plows, and seeders for soil cultivation and planting, to complex harvesters, balers, and irrigation systems for crop management and collection. The primary objective is to enhance agricultural productivity, improve efficiency, reduce labor requirements, and support sustainable farming practices through mechanization and automation.
