Tractor Maintenance Points and Skills

Tractor A self-propelled engine used to pull and drive work machinery for various mobile tasks. It can also do fixed power. A tractor consists of an engine, transmission, walking, steering, hydraulic suspension, power take-off, electrical instruments, drive control and traction systems or devices. The power of the engine is transmitted to the drive wheels through the transmission system to make the tractor start. Before spring ploughing, many farmers with agricultural machinery also began to maintain and maintain the agricultural machinery. Here we remind farmers who use tractors to pay attention to the problems and not to ignore the problems in the maintenance process.

1. Main points of tractor maintenance

1. It is forbidden to start and lift the clutch roughly. The clutch pedal should be released slowly and the accelerator should be increased appropriately. Otherwise, it will cause shock to the clutch and transmission parts, or even damage.

2. The tractor is strictly prohibited from idling or slipping off the clutch.

3. Selection of tractor gear shift and working speed. The correct choice of the working speed of the tractor can not only obtain good productivity and economy, but also prolong the service life of the tractor. When the tractor is working, it should not be overloaded frequently, so that the engine has a certain power reserve. The choice of tractor field working speed should make the engine work at about 80% load.

Second, the tractor maintenance skills

1. The oil pan only depends on the quantity, not the quality. Some drivers only know how to refill oil, but ignore the quality inspection. As everyone knows, the oil used for a long time contains a lot of oxides and metal chips, which leads to the decline of lubricating performance and the wear of parts. Therefore, the engine should be replaced regularly according to the prescribed cycle.

2. Only maintain the air filter, not the exhaust pipe and muffler. Some drivers never clean the carbon deposits on the exhaust pipe and muffler, resulting in excessive carbon deposits and reduced exhaust cross-sectional area, resulting in unclean exhaust, insufficient fresh air and worse combustion.

3. Cooling water only needs to be added, regardless of the cooling effect. Some drivers never clear the scale, and although the cooling water is sufficient, the cooling effect is poor, causing various failures.

4. Only pay attention to the quality of the plunger and nozzle needle valve parts, not the quality of the oil valve parts. The function of the oil outlet valve is to seal and separate the oil cavity of the plunger from the high-pressure oil pipe to avoid backflow; the second is to stop the oil supply during rapid decompression to ensure that the nozzle is simply cut off. Many failures of diesel engines are caused by poor quality or wear of valve couplers.

5. Only pay attention to the state of the valve and valve seat, not the quality of the valve spring. When a valve leaks, people are accustomed to checking the valve and valve seat, ignoring the quality of the valve spring. It should be pointed out that the insufficient elasticity of the valve spring is also one of the reasons for the valve leakage failure.

In real life, tractors often use rubber belts as power transmission media. According to the function and purpose of agricultural, industrial and special purpose tractors; according to the structure type, it is divided into wheeled, crawler, boat tractor and chassis type. The above are the maintenance points and skills of tractors for your reference and hope to be helpful to you.
