What is agriculture? Agriculture is the science or art of cultivating the soil, growing and harvesting crops, and raising livestock. The art of making land more productive is practiced throughout the world – in some areas by methods not far removed from the conditions of several thousands of years ago and in other areas with the aid of science and mechanization, as a highly commercial type of endeavor. Agriculture still drafts into its service more of the world’s aggregate manpower than all other occupations combined.
The two main types of tractors are wheeled, which is the earliest form, and continuous track. Tractors are used in agriculture, construction, road building, etc., in the form of bulldozers, scrapers, and diggers. A notable feature of tractors in many applications is the power-takeoff accessory, used to operate stationary or drawn machinery and implements.
