In the rice planting areas of our country, wheeled tractors often experience problems such as slipping and wheel sinking during operation, which makes it difficult to utilize the tractor's power and seriously damages the soil structure. In mountainous areas with steep ground slopes, the climbing ability of ordinary tractors is limited, and their stability and traction efficiency are affected when walking or attaching agricultural tools. Therefore, tracked or semi tracked tractors have more advantages in paddy fields and mountainous operations

There are some problems with the use of wheeled tractors in current agricultural production. For example, in the Northeast Longzuo area, when using wheeled tractors for shoveling operations, there is severe trenching, which affects the quality of the operation; In addition, some areas in Heilongjiang Province experience thawing in spring and heavy rainfall in autumn, resulting in high soil moisture content. The traction and adhesion performance of wheeled tractors significantly decreases, and they may even be unable to carry out operations. Therefore, many comrades believe that wheeled tractors are not suitable for ridge farming and are not suitable for field operations in Heilongjiang Province;
