Agricultural Machinery, machines used to till soil and to plant, cultivate, and harvest crops. Since ancient times, when cultures first began cultivating plants, people have used tools to help them grow and harvest crops. They used pointed tools to dig and keep soil loosened, and sharp, knife-like objects to harvest ripened crops. Modifications of these early implements led to the development of small hand tools that are still used in gardening, such as the spade, hoe, rake and trowel, and larger implements, such as ploughs and larger rakes that are drawn by humans, animals, or simple machines.
Much of the world's arable land is still tilled under conditions that do not permit use of expensive modern machinery. However, modern machinery is used extensively in Western Europe, Australia, the United States, and Canada.
