Classification standards of agricultural machinery

Agricultural machinery is generally classified by purpose. Most of these machines are specially designed and manufactured according to the characteristics of agriculture and the special requirements of various operations, such as soil tillage machinery, planting and fertilization machinery, plant protection machinery, crop harvesting machinery, animal husbandry machinery, and agricultural product processing machinery. Another part of agricultural machinery is common to other industries and can be directly selected according to the characteristics and needs of agriculture, such as agricultural power machinery, water pumps in farmland irrigation and drainage machinery, etc.; or these machines can be designed into agricultural variants according to the characteristics and needs of agriculture, such as agricultural vehicles and trailers in agricultural transportation machinery, and earth and stone machinery in farmland construction machinery.
Agricultural machinery can also be classified according to the power used and its matching method. The power used in agricultural machinery can be divided into two parts: one part is used for the walking or movement of agricultural machinery, which can be divided into human power (hand-held, back-carried, chest-hanging, and push-pull), animal-powered traction, tractor-powered traction, and self-propelled types; the other part is used to drive the working parts of agricultural machinery, which can be divided into human power (hand-cranked, pedaled, etc.), animal-powered, electromechanical power (using internal combustion engines, wind turbines, electric motors, etc.) and tractor-driven types. On the same agricultural machinery, these two parts can use the same or different power. According to the matching mode of agricultural machinery and tractors, it can be divided into traction, suspension, and semi-suspension types.
According to the operation mode, agricultural machinery can be divided into two categories: walking operation and fixed operation. Among the agricultural machinery for walking operation, there are two types: continuous walking type that operates in the continuous travel process and intermittent walking type that alternates between travel and operation. Among the agricultural machinery for fixed operation, there are two types: movable type that can move the operation site in the non-operating state and immovable type whose operation site is always fixed.
According to the operation location, agricultural machinery is divided into field operations (fields, pastures and orchards, etc.), yard operations, indoor operations (factories, machine rooms, warehouses, greenhouses and poultry houses, etc.), underwater or water operations (rivers, channels, reservoirs and wells, etc.), road operations and aerial operations.
