Farm equipment mechanics repair and adjust equipment that is not working correctly. They also do preventive maintenance. Today's farm is typically much larger than in the past. Therefore, most types of farms use specialized machines. These machines have grown in variety, complexity, and size.
Many farms have several tractors.
Self-propelled combines, swathers, planters, grain augers, elevators, hay balers, crop dryers, tillage equipment, and manure spreaders are common, as well as irrigation and spray equipment. The machinery has more hydraulic and electronic controls than before. Therefore, farmers have increasingly turned to farm equipment mechanics to repair and service the machines. Some of these mechanics are called service technicians. They are employed by farm equipment dealers.
