What are the development trends of agricultural tractors?

An agricultural tractor is basically a machine that provides mechanical power to perform agricultural tasks. Tractors can be used to pull various agricultural implements for plowing, planting, deep plowing, 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 have an absolute advantage among agricultural tractors. Crawler tractors are basically no longer used for agricultural production in many countries; although some crawler tractors are still in use in the Soviet Union, Italy, and China, their proportion is also declining. In industrial tractors, especially bulldozers, excavators, and other models, crawler types still have an absolute advantage. As tractor power increases, four-wheel-drive tractors have developed rapidly. The application of hydraulic steering devices has solved the steering difficulties of such models, and articulated steering can greatly reduce the turning radius. These factors have further promoted the development of high-power four-wheel-drive tractors. In order to improve traction and adhesion performance and passing ability in rice fields, four-wheel-drive variants of small and medium-power wheeled tractors have also developed rapidly in Japan and other countries. 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 the corresponding operations. Therefore, agricultural machinery operating units should reasonably select supporting implements for tractors to give full play to the role of the tractor. Existing matching categories 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 the rolling resistance of agricultural tractors play? The rolling resistance of agricultural tractors is mainly caused by the deformation of tires and soil. Under the action of the tractor's weight, the tires are flattened and the soil is compacted; during the rolling process of the wheel, the part of the tire in contact with the ground along the circumference is flattened and deformed in turn, and the higher soil in front of the wheel is pressed down, causing the soil to deform and form ruts. This is the rolling resistance that hinders the wheel's forward movement. There are many factors affecting rolling resistance, mainly related to the firmness of the ground and the size of the vertical load. For the same tractor, if the ground conditions are different, its rolling resistance is also different. For example, when driving on asphalt, cement, or dry hard ground, the rolling resistance is relatively small, and the tractor's driving force (traction force) is large; the softer the ground and the greater the vertical load, the greater the vertical deformation of the soil and the greater the rolling resistance. Generally speaking, reducing the deformation of the tire itself and the vertical deformation of the soil is beneficial for reducing rolling resistance. If the tractor is driving on soft ground, using low-pressure tires and increasing the tire contact area can reduce the vertical deformation of the soil, lower rolling resistance, and thereby improve traction. Since tractors are mainly used for field operations and mostly travel on soft ground, in order to reduce the vertical deformation of the soil, tractors generally use tires with the lowest pressure, which is the same principle as using widened tires. In our operations, we should pay attention to the differences in the use of low-pressure tires, widened tires, and high-pressure tires.
