The main factors affecting the driving of tractors in Nanchang
(1) The rolling resistance of a tractor is mainly caused by the deformation of the tires and soil. Under the weight of the tractor, the tires are flattened and the soil is compacted. During the rolling process, the various parts of the tire that come into contact with the ground along the circumference of the circle are continuously flattened and deformed, and the soil in front of the wheel is pressed down to deform the soil and form wheel tracks, which generate rolling resistance that hinders the forward rolling of the wheel. There are many factors that affect rolling resistance, mainly related to the size of the vertical load on the solid and moist ground. 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 small, and the tractor traction is large. Under the same usage conditions, the greater the weight added to the tires, 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 driven on soft ground, using low-pressure tires and increasing the tire support area can reduce soil deformation in the vertical direction, lower rolling resistance, and thus improve traction. Due to the fact that tractors are mainly used for field operations and often drive on soft ground, in order to reduce soil deformation in the vertical direction, tractors generally use low-pressure tires, and the same principle applies to widened tires. We should pay attention to the differences in the use of low-pressure tires, widened tires, and high-pressure tires in our operations.
