What are the development trends in agricultural tractors?

An agricultural tractor is essentially a machine that provides mechanical power to perform agricultural tasks. Tractors can be used to pull various agricultural implements for plowing, planting, deep tillage, fertilizing, and harvesting crops, as well as for transporting materials and serving as personal transportation. What are the development trends of agricultural tractors? Wheeled tractors hold an absolute advantage among agricultural tractors. Crawler tractors have largely ceased to be used in agricultural production in many countries; in the Soviet Union, Italy, and China, although some crawler tractors are still in use, their proportion is also declining. However, in industrial tractors, especially bulldozers, excavators, and similar models, crawler tracks still maintain an absolute advantage. With the increase in tractor power, four-wheel-drive tractors have developed rapidly, and the application of hydraulic steering devices has solved the steering difficulties of such models, while articulated steering can greatly reduce the turning radius—these factors have further promoted the development of high-power four-wheel-drive tractors. To improve traction performance and passability in paddy fields, four-wheel-drive variants of small and medium-power wheeled tractors have also developed rapidly in countries such as Japan. Can agricultural tractors be matched with agricultural implements? An agricultural tractor is a self-propelled agricultural power machine that needs to be paired with various agricultural implements to complete corresponding operations. Therefore, agricultural machinery operating units should rationally select matching implements for tractors to fully leverage the tractor's capabilities. Existing matching configurations can be divided into 8.8 kW (12 hp) walking tractors, 8.8–11 kW (12–15 hp) small four-wheel tractors, 18.4 kW (25 hp) four-wheel tractors, 36.8 kW (50 hp) four-wheel tractors, 40.4–47.8 kW (55–65 hp) four-wheel tractors, and so on. What role does rolling resistance play in agricultural tractors? The rolling resistance of an agricultural tractor is mainly caused by the deformation of tires and soil. Under the weight of the tractor, the tires are compressed and the soil is compacted; during wheel rotation, the part of the tire in contact with the ground along its circumference is successively flattened and deformed, and the higher soil in front of the wheel is pressed down, causing soil deformation and forming ruts—this is the rolling resistance that hinders wheel forward motion. There are many factors affecting rolling resistance, mainly related to the firmness of the ground and the magnitude of vertical load. For the same tractor, if ground conditions differ, its rolling resistance also differs. For example, when driving on asphalt, cement, or dry hard ground, rolling resistance is smaller, and the tractor's driving force (traction) is greater; the softer the ground and the greater the vertical load, the greater the soil deformation in the vertical direction, and the greater the rolling resistance. Generally speaking, reducing the deformation of the tire itself and the vertical deformation of the soil helps lower rolling resistance. If the tractor travels on soft ground, using low-pressure tires and increasing the tire contact area can reduce vertical soil deformation, lower rolling resistance, and thereby improve traction. Since tractors are mainly used for field operations and mostly travel on soft ground, to reduce vertical soil deformation, tractors generally use tires with the lowest pressure, which is the same principle as using wider tires. In our operations, attention should be paid to the differences in use among low-pressure tires, wide tires, and high-pressure tires.
