Field vehicles are machines used to work on land, such as farms, ranches, and other agricultural areas. The most common field vehicle is the tractor, which is a motorized vehicle with large, back wheels that is used to pull or push heavy loads. Tractors are used for a variety of tasks, including plowing, tilling, planting, harvesting, and hauling. They can also be used to power other machines, such as mowers, balers, and combines.
