Agriculture is the cultivation of animals, plants and other life forms for food, fiber, and other products used to sustain life.
Today’s crop farms require a high level of mechanization to prepare the fields, planting and harvesting. Likewise, farms that raise animals also benefit from machinery.
A tractor is a vehicle specifically designed to deliver a high tractive effort or torque at slow speeds, for the purposes of hauling machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage but nowadays a great variety of tasks. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanized.
The combine harvester, or simply combine, is a machine that harvests grain crops.
In agriculture, a sprayer is a piece of equipment that use spray nozzles to apply herbicides, pesticides, and fertilizers to agricultural crops. Sprayers range in size from pull type to self-propelled units similar to tractors with boom mounts of 60–151 feet in length.
A baler is a piece of farm machinery used to compress a cut and raked crop (such as hay, straw, or silage) into compact bales that are easy to handle, transport and store. Several different types of balers are commonly used, each producing a different type of bales – rectangular or cylindrical, of various sizes, bound with twine, netting, or wire.
There are four general types of harrows: disc harrow, tine harrow, chain harrow and chain disk harrows. Harrows were originally drawn by draft animals, such as horses, mules, or oxen. In modern practice they are almost always tractor-mounted implements, either trailed after the tractor via a drawbar or mounted on the three-point hitch.
