Compared with large and medium-sized rubber tire tractors, small four-wheel tractors have a much shorter service life. However, the tires currently produced, except for special applications, are generally of the same material regardless of their size. The tire life of a small four-wheel tractor is so short? This is mainly determined by its characteristics. Understanding the characteristics of the small four-wheeled rounds and taking corresponding preventive measures are very necessary for the farmer. First, the main features 1. Structural features. The drive wheels of most small four-wheel tractors are fixed on the axles in a flanged manner. This structure makes the adjustment of the wheel pitch of the driving wheels very limited, and thus the poor adaptability to the characteristics of the road surface, especially When the large and medium-sized tractors run over deeper ruts or work on ridges in the direction of furrows, they are often in a “tired†state, which exacerbates tire wear. 2. Use features. Due to its small size, light weight, easy operation, wide range of use, and high maneuverability, the small four-wheel tractor is easier to damage the tire than the large and medium tractors in the following aspects. 1 There are many work projects and the work environment is poor, so there are many opportunities for friction, squeezing, impact and erosion. 2 Low load capacity, often under overloaded operation. 3 It is small and easy to operate, so that people who do not understand maintenance technology can also operate. Operators can't find the signs of tire damage in time, and it is difficult to ensure that the tires work in good condition. 3. Management characteristics. Small four-wheel tractors are basically all owned by individuals and there is no top-down management system. Operators only use them, and they do not pay attention to maintenance. Second, preventive measures 1. Regularly check the technical status of the parts related to the tire, such as the state of the rim, the bead, and the wheel body (generally the front wheel body, etc.). Also check the technical status of components that have a major influence on the tire, such as the technical status of the axles, front axles, frames, and bearings of the traveling mechanism. Find problems that need to be adjusted and repaired in a timely manner. 2. Avoid contact with kerosene, diesel oil, strong acids, alkalis, and hot objects. 3. Avoid tire pressure on objects that are prone to device damage, such as iron filings, barbed iron, broken glass. 4. Try to drive on the road suitable for small four-wheel tractors. 5. If you do a certain job for a long time, you should adjust the tire installation status and tire type as required. 6. Reasonable use of weight. In the field traction operation, the counterweight should be increased; in the road transport, the counterweight should be reduced. Also don't sit on the wheel fenders or carry other heavy objects. 7. Master the tire air pressure. For small four-wheel tires, do not run out of gas (field operations may be slightly lower, and road transport should be sufficient). For a long period of time, it is advisable to lift the frame so that the tire is not or less affected by the gravity of the locomotive. At this time, the air pressure inside the tire can be kept to the normal working pressure, and the tire is grounded periodically (ie, rotated). When parking for a long time, the rack should be lifted to completely remove the tire from the ground, release the gas in the tire or keep it below 1/5 of the normal working pressure, and also remove the tire assembly, keep it in a safe place and take care to avoid being squeezed. Sun and rain. 8. When driving in a hilly area or a mountainous area, the pressure on the ground is reduced due to the up and down slopes, and the relative slipping of the tire to the ground is prone to occur, which aggravates the wear of the tire. In this case, the anti-skid chain can be added. When the anti-skid chain cannot be added, the counterweight of the drive wheel can be appropriately increased, and the traction load can also be appropriately reduced. 9. If it is found that the tire has serious device damage, repair it in time. When the tread wear is serious, it should be promptly sent to the repair department for renovation. 10. If, due to long-term operation, tires are subject to regular uneven wear, the left and right tire positions should be reversed so that the tires are uniformly worn.
