There are some problems with the use of wheeled tractors in current agricultural production. For example, when using wheeled tractors for shoveling operations in the northeast ridge farming area, there is severe ditch pressure, which affects the quality of the operation; In addition, some areas in Heilongjiang Province experience freezing in spring and heavy rainfall in autumn, resulting in high soil moisture content and a significant decrease in the traction and adhesion performance of wheeled tractors. Therefore, many comrades believe that wheeled tractors are not suitable for ridge farming and are not suitable for field operations in Heilongjiang Province;

To improve the traction and adhesion performance of wheeled tractors, as well as the passability or anti sinking performance of self-propelled Compaynes, various forms of modifications can be made to their walking devices, one of which is to modify them into a half track walking device
